Engine & Performance For The Ram 1500 TRX
Cold air intakes, tuners, and bolt-ons that wake up the TRX's supercharged 6.2L HEMI V8 — more power, sharper throttle response, and a louder blower whine on top of 702 factory horses.

The TRX arrives with 702 hp and 650 lb-ft from a supercharged 6.2L HEMI, which puts it in an unusual position: it is one of the few trucks where the factory calibration is genuinely aggressive and the low-hanging bolt-on fruit is already picked. The upgrades that move the needle here are about airflow, heat and calibration, in that order.
A sealed cold air intake with the right filter media is the sensible first move, especially on a truck that eats dust. Beyond that the honest conversation is heat management — a supercharged engine that heat-soaks pulls timing and gives power back — then tuning, then pulley and fuelling work for owners who genuinely want more. Start with the cold air intake guide and the performance upgrade rankings.
TRX Powertrain Reference
- Engine
- 6.2L supercharged HEMI V8 — Hellcat-derived
- Output
- 702 hp / 650 lb-ft from the factory
- Transmission
- ZF-sourced 8-speed automatic — uses a specific ATF spec, never a generic bottle
- Oil
- Full-synthetic 0W-40 meeting Chrysler MS-12633
- Supercharger
- Runs its own separate supercharger oil, distinct from engine oil
- Spark plugs
- Eight platinum/iridium plugs; boost wears them faster than the generic "lifetime" charts suggest
Before You Buy Engine & Performance For A TRX
- Prefer a sealed airbox intake over an open-element cone on a truck that sees dust — filtration matters more than a marketing lumens-style airflow number.
- Dry synthetic vs. oiled cotton filter media is a real choice: oiled media can foul a MAF sensor if over-oiled after cleaning.
- Any tune changes what your plugs need. Tuned trucks commonly step to a colder heat range — talk to your tuner before chasing a misfire.
- Heat soak is the real enemy on a supercharged engine. Cooling upgrades often return more usable power than another airflow part.
- Check emissions legality for your state before buying tunes or intake hardware that alters emissions equipment.
