Answers to the most common questions before choosing an intake.
Which intake style should I choose?
Pick RHI if you want a heat-shielded filter in the engine bay with an easy 30–60 minute install — it's the best all-rounder for daily drivers, trucks and SUVs. Choose RCI (cold air) if you want the filter placed far from engine heat for the coolest intake charge. Go RSI (short ram) if you want the simplest install, the lowest price, and the most aggressive intake sound.
What's the difference between a heat shield intake and a cold air intake?
Both replace the restrictive factory airbox. A heat shield intake (RHI) keeps the filter in the engine bay but walls it off from radiant heat with a vehicle-specific shield. A cold air intake (RCI) uses longer piping to relocate the filter entirely — usually to the fender well — where the air is cooler. RHI installs faster; RCI typically draws cooler air.
How do I confirm an intake fits my vehicle?
Match your exact year, make, model, engine size (e.g., 5.3L V8) and trim against the fitment on the product page. If anything's unclear — transmission, sensor type, or a mid-year split like the 2007 Silverado Classic vs. new body style — contact us before ordering and we'll confirm.
Will an intake add horsepower?
An intake reduces restriction versus the stock airbox, which sharpens throttle response and usually frees up a few horsepower — but no honest seller can promise an exact number for every vehicle. Gains depend on your engine, supporting mods, and installation. What every driver notices immediately is the deeper intake sound under acceleration.
Do I need a tune after installing one of these intakes?
No tune is required — every Rtunes premium intake is a direct bolt-on that installs and runs on the factory tune. But if you want to fully utilize the kit and get its full performance potential, a tune is recommended.
Can I run one of these intakes in California?
It depends on the product and vehicle. Check the product page for current CARB EO status or geographic restrictions before ordering — some kits are not legal for sale or use in California and other CARB states.
