An Infiniti Q60 intercooler upgrade is the single most cost-effective way to unlock consistent power from the twin-turbo VR30DDTT. The 2017–2022 Q60 Red Sport 400 leaves the factory with 400 horsepower and 350 lb-ft, but its compact factory air-to-water charge coolers heat-soak within a few hard pulls — and once intake air temperatures climb, the ECU quietly pulls timing and boost. In our Tampa shop the fix that pays for itself first is the Mishimoto air-to-water intercooler kit, backed by the matching Mishimoto performance heat exchanger. This review breaks down the specs, the real-world temperature and power numbers, fitment, and whether it is worth it for your Q60.
Our Verdict
The Mishimoto air-to-water intercooler kit is the best first cooling mod for the VR30-powered Infiniti Q60.
It drops charge-air temperatures up to 23°F, adds up to 8 HP and 12 lb-ft with no retune, and uses leak-proof cast aluminum end tanks — all under a Mishimoto Lifetime Warranty. Pair it with the performance heat exchanger to keep the water side cool on track days and back-to-back pulls.
Shop Our Top Pick →What Is the VR30 Charge-Cooling System and Why Does It Heat Soak?
The VR30DDTT is a 3.0-liter twin-turbo V6 that uses a factory air-to-water (water-to-air) charge-cooling system instead of a traditional front-mount intercooler. Two compact intercooler cores sit on top of the engine, a dedicated coolant loop pulls heat out of them, and a small heat exchanger behind the front bumper sheds that heat to the air. It is a clever packaging solution, but the cores and the front heat exchanger are sized for the base 300-horsepower tune — not for the 400-horsepower Red Sport 400 driven hard.
Heat soak is the result. On the street the factory system is fine, but string together a few wide-open pulls, a dyno session, or a canyon run and the coolant loop saturates. Intake air temperatures spike, the ECU responds by cutting ignition timing and boost to protect the engine, and the car feels progressively softer. Owners describe it as the Q60 “falling on its face” on the second and third pulls. Upgrading the charge coolers and the heat exchanger is how you turn those inconsistent, temperature-limited runs into repeatable power.
The Mishimoto cores replace the factory VR30 charge coolers that sit on top of the engine.
Mishimoto Q60 Air-to-Water Intercooler Kit Review
The Mishimoto Performance Air-to-Water Intercooler Kit is a direct replacement for both factory VR30 charge coolers. Mishimoto increases core volume and switches to cast aluminum end tanks, which eliminate the welded-seam leak points and stress concentrations that can develop under sustained high boost. The kit is a genuine bolt-on: it includes the ancillary hoses, couplers, and engine-cover spacers so the extra cooling capacity hides under the factory engine cover for a completely stealth install.
The headline numbers are the reason this kit sells. Mishimoto measured dyno-proven charge-air temperatures up to 23°F cooler than stock, and because colder, denser air lets the VR30 make the most of every drop of fuel, the company recorded gains of up to 8 HP and 12 lb-ft without a retune. Add a calibration and the cooler intake temps let a tuner run more aggressive timing and boost with a smaller safety margin, so the practical gain on a tuned Red Sport 400 is larger still. At roughly $1,785 with free shipping, it is the highest-value hard part you can bolt to a VR30 before stepping up to downpipes or a full tune.
Cast aluminum end tanks eliminate the welded-seam leak points found on lesser designs.

Air-to-Water vs. Front-Mount: Why Mishimoto Keeps the Factory Layout
A common question we hear in the shop is why the Q60 does not just get a big front-mount intercooler. The answer is packaging and response. An air-to-water system puts the charge coolers inches from the throttle bodies, so there is very little plumbing volume between the turbos and the engine — that means sharper throttle response and faster boost recovery than a long-piped front-mount. It also lets the coolant loop briefly absorb a heat spike that air alone could not, which is ideal for the street and for short bursts.
The trade-off is thermal capacity: an air-to-water system is only as good as its coolant volume and its heat exchanger. That is exactly why Mishimoto upgrades both the cores and the front heat exchanger rather than abandoning the factory architecture. You keep the VR30’s excellent transient response and stealth looks while roughly doubling the system’s ability to shed heat. For a daily-driven, occasionally-tracked Q60 Red Sport 400, that is the smartest balance of response, reliability, and repeatable power.
The kit includes the ancillary hoses and couplers needed for a complete, leak-free install.
The Missing Half: Mishimoto Performance Heat Exchanger
Upgrading the intercooler cores only solves half of the equation. The charge coolers can only dump heat as fast as the front heat exchanger sheds it to the air, and the factory heat exchanger is the true weak link: it is a small core feeding two intercoolers, and it uses plastic end tanks that raise long-term durability questions. On sustained runs it becomes the bottleneck that lets coolant temperatures — and therefore intake temperatures — creep up.
Mishimoto’s answer is a dramatically larger core: a 196% increase in core volume and a 97% increase in external fin surface area over the stock unit, built with all-aluminum TIG-welded construction in place of the plastic tanks. A removable outlet port and a captive bleeder valve make bleeding the coolant loop far easier during installation. The payoff is up to a 21°F drop in outlet temperatures, which keeps the entire air-to-water system from saturating. At around $600 with free shipping, it is the logical companion to the intercooler kit — run both and the VR30 holds its power across repeated pulls instead of tapering after the first.

Installation, Fitment and Tuning Notes
Both upgrades are direct-fit bolt-ons for the 2016–2022 Infiniti Q60 and Q50 3.0T, covering Base, Luxe, Pure, Sport, Red Sport, and Red Sport 400 trims running the VR30DDTT. The intercooler kit ships with all required hoses, couplers, and engine-cover spacers; plan on a few hours of shop time to remove the intake plumbing, swap the cores, and refill and bleed the coolant loop. The heat exchanger’s captive bleeder valve and removable outlet port make that bleed step much simpler.
At NLP Performance in Tampa, FL, we recommend installing the intercooler and heat exchanger together if the car will see any track or spirited use — the cores and the heat exchanger work as a system, and doing both in one visit means one bleed and one alignment of downtime. No tune is required to benefit, but if you later add a calibration, the cooler, denser intake charge is what lets a tuner safely chase bigger boost and timing numbers. Remember the intercooler kit cannot ship to California addresses due to CARB regulations.

Is a Q60 Intercooler Upgrade Worth It?
For the money, a Q60 intercooler upgrade is one of the best value modifications you can make to a VR30-powered car. The problem it solves — heat soak that steals power on the second and third pulls — is universal to the platform and gets worse with every additional modification. Where a set of downpipes or a tune adds peak power that the factory cooling system then struggles to sustain, the intercooler and heat exchanger make sure the power you paid for actually shows up run after run. That consistency is why cooling is the mod experienced VR30 owners tell newcomers to do first.
The honest counterpoint: if your Q60 never sees more than an occasional highway pull and you have no plans to tune it, the factory system will keep up and the upgrade is optional. But the moment you add boost, do repeated 40–100 mph runs, or take the car to a track day or dyno, the difference is immediate and repeatable. In our experience at NLP Performance, the owners who install the Mishimoto cooling package alongside their first tune are the ones who never come back complaining that the car “feels slower when it is hot.” Both parts are in stock with free shipping, so you can bundle the intercooler and heat exchanger and handle the whole cooling system in one install.
Included engine-cover spacers let the upgraded cores hide under the factory cover for a stealth look.
Frequently Asked Questions
Does the Infiniti Q60 need an intercooler upgrade?
Yes — any tuned or hard-driven Q60 3.0T benefits from an intercooler upgrade. The factory VR30 air-to-water charge coolers heat-soak within a few pulls, causing the ECU to pull timing and boost. The Mishimoto kit drops charge-air temps up to 23°F to restore consistent power.
How much horsepower does the Mishimoto Q60 intercooler add?
Mishimoto measured up to 8 HP and 12 lb-ft of torque with no retune on the 2016+ Q50/Q60 3.0T, purely from cooler, denser intake air. With a supporting tune the practical gain is larger, because lower intake temperatures let a calibrator run more aggressive timing and boost.
What engine does the Infiniti Q60 use?
The 2017–2022 Infiniti Q60 uses the VR30DDTT, a 3.0-liter twin-turbo V6. It makes 300 horsepower in base 3.0t form and 400 horsepower with 350 lb-ft in the Red Sport 400. The same engine powers the Q50 sedan.
Do I also need the Mishimoto heat exchanger?
For street driving the intercooler kit alone is a big improvement, but for track days, dyno sessions, or a tuned Red Sport 400 the heat exchanger is strongly recommended. It adds 196% more core volume and drops outlet temperatures up to 21°F, preventing the coolant loop from saturating.
Is the Mishimoto Q60 intercooler kit CARB legal?
No. The Mishimoto Performance Air-to-Water Intercooler Kit cannot be shipped to California because it is not CARB-certified. Customers outside California can install it without emissions restrictions, and it carries the Mishimoto Lifetime Warranty.
How much does a Q60 intercooler upgrade cost?
The Mishimoto Performance Air-to-Water Intercooler Kit runs around $1,785 and the matching Performance Heat Exchanger about $600, both with free shipping at NLP Performance. Buying the pair is the complete cooling solution for a VR30-powered Q60.
