Best Throttle Bodies for 2013-2020 Dodge Challenger HEMI

A throttle body upgrade is one of the cheapest bolt-ons that lets a modified 2013-2020 Dodge Challenger or Charger HEMI breathe the way its builder intended. The best throttle bodies for the 2013-2020 Dodge Challenger HEMI replace the factory 80mm drive-by-wire unit with a 85mm, 90mm, or 95mm CNC-billet bore, feeding more air to the 5.7L and 6.4L V8 at wide-open throttle. In this guide we compare the parts we actually sell and install at NLP Performance in Tampa, FL, with real bore specs, fitment, CARB status, and honest advice on when a bigger throttle body pays off.

What Does a Throttle Body Do on a Gen III HEMI?

A throttle body is the electronically controlled valve between the air intake and the intake manifold that meters how much air enters the engine. On the 2013-2020 Challenger and Charger, the 5.7L and 6.4L HEMI use a drive-by-wire (DBW) throttle body with roughly an 80mm bore — there is no cable, so the pedal commands a motor that opens the throttle blade. Enlarging that bore to 85mm, 90mm, or 95mm reduces the restriction at wide-open throttle, which lets the engine draw a larger volume of air when the rest of the airflow path can use it.

Here is the honest part most listings skip: on a bone-stock 5.7L R/T, a bigger throttle body is worth only a few horsepower. The gains show up when air can actually move — a cold air intake, a ported or aftermarket intake manifold, long-tube headers, a bigger camshaft, or forced induction. On a modified 6.4L 392, our dyno experience and manufacturer testing put a throttle body swap in the 5-12 horsepower range, with sharper throttle response drivers feel immediately. Think of it as the mod that removes a ceiling, not one that makes power on its own.

Which Bore Size Is Right for a 5.7L vs 6.4L HEMI?

Match the bore to your displacement and how far the build has gone. The 5.7L (345 cubic inch) HEMI in the R/T — roughly 370-375 hp from the factory — responds best to the 85mm bore, which keeps intake velocity high for strong low-end and mid-range throttle response on a stock or mildly modified engine. The 6.4L (392 cubic inch) HEMI in the Scat Pack and SRT 392 — 470 hp on 2011-2014 SRT8 cars and 485 hp on 2015-2020 Scat Pack/392 cars — has the displacement to use the 90mm or 95mm bore, especially once it has an intake, headers, and a tune.

A good rule of thumb from our shop: go 85mm for a stock-to-mild 5.7, 90mm for a modified 5.7 or any 6.4, and 95mm only when you are chasing a cam, big heads, or boost. Oversizing the bore on an otherwise stock engine can actually blunt throttle tip-in, so bigger is not automatically better.

The Best Throttle Bodies for 2013-2020 Challenger & Charger HEMI

Every throttle body below is in stock and buyable at NLP Performance and fits the 2013-2020 Challenger and Charger 5.7L and 6.4L HEMI (the BBK and Granatelli units also fit the Chrysler 300, Durango, Grand Cherokee, and Ram with the same engines). Prices shown update live from our store.

1. BBK 90mm Power Plus — Best Overall

The BBK 90mm is our default recommendation because it hits the sweet spot for the widest range of builds. It is CNC-machined from billet aluminum with a progressively tapered bore for a smooth transition into the manifold, and it ships pre-matched so it runs without a tune on these HEMIs. It is also the only unit in this guide that carries a CARB Executive Order (for 2013-2016 model years), so it stays 50-state street legal on those cars. On a Scat Pack with an intake and a tune, expect crisper throttle tip-in and a few extra horsepower up top.

2. BBK 85mm Power Plus — Best for the 5.7L R/T

The 85mm shares the same billet construction, no-tune fitment, and CARB EO (2013-2016) as the 90mm, but its slightly smaller bore keeps air velocity up on the 5.7L R/T. If your Challenger or Charger is stock or lightly modified, this is the one we hand you — it sharpens pedal response without the risk of soft tip-in that an oversized bore can cause on a smaller-displacement engine. It is about $20 cheaper than the 90mm, too.

3. Granatelli 95mm Malevolent DBW — Budget Pick & Biggest Bore

If you want the biggest bore for the least money, the Granatelli Malevolent is the value play at around $445 — the cheapest unit in this guide and the only one under $500. Its 95mm billet bore and blacked-out finish suit a heavily built or boosted 6.4L that can genuinely use the extra flow. It is sold off-road only in California, so confirm your local emissions rules. We only recommend the 95mm when the engine has the cam, heads, or boost to support it; on a stock car the 85mm or 90mm will drive better.

4. BLOX 105mm Electronic — For the Supercharged 6.2L Hellcat

A Hellcat is still a Challenger, so it earns a spot here — but read this carefully. The supercharged 6.2L Hellcat and Grand Cherokee Trackhawk use a completely different, larger 105mm electronic throttle body. The BBK and Granatelli 5.7/6.4 units above will not fit it, and this BLOX 105mm will not fit your 5.7 or 6.4 N/A car. If you have a 707-717 hp Hellcat and want more airflow for a pulley or e85 combo, this billet 105mm is the right part; for everyone else, stay with the 85mm, 90mm, or 95mm.

Here is every option side by side. The CARB column is the key legality axis for California drivers; bore and engine fit decide which one actually belongs on your car.

How to Install a HEMI Throttle Body

Installing a drive-by-wire throttle body on the 2013-2020 Challenger or Charger takes about 30-45 minutes with basic hand tools. Disconnect the negative battery terminal, unclip the single electrical connector on the throttle body, remove the four retaining bolts, and lift the factory unit off the intake manifold. Transfer the gasket or o-ring if required, bolt the new billet body in place, reconnect the plug, and reconnect the battery. Because the throttle is electronic, the PCM needs a short idle relearn — turn the key to run for about 30 seconds without starting, then start the car and let it idle for a few minutes so the computer relearns the throttle position.

The BBK units are size-matched and designed to run without a tune. If you pair the throttle body with a cold air intake, a ported manifold, or headers, a custom tune will let you recover every bit of the airflow and dial in throttle mapping. Not comfortable with the relearn or want it dyno-verified? Our Tampa shop handles throttle body and tune installs daily.

Do You Actually Need a Bigger Throttle Body?

A throttle body is a supporting mod, not a standalone power-maker. On a stock 5.7L R/T you will feel sharper throttle response but see only a few horsepower. The HEMI owners who get the most out of this upgrade have already added a cold air intake, an aftermarket or ported intake manifold, long-tube headers, a camshaft, or a supercharger — the throttle body then stops being the bottleneck. If you are early in your build, pair the throttle body with an intake and a tune for the best bang for the buck, then add it to a headers-and-cam combo later. That staged approach is what we steer most of our Challenger and Charger customers toward.
