Fitment Information
- 2025 Toyota 4Runner (6th Gen, N500)
- 2026 Toyota 4Runner (6th Gen, N500)
Fitment Note
Fits 2025-2026 6th Gen Toyota 4Runner, gas or i-FORCE MAX hybrid, all trims. No tuning needed on most trims, but Trailhunter and TRD Pro models do require tuning after install. Does not seal watertight against the factory snorkel, if your 4Runner has one, confirm compatibility before ordering. Not yet CARB compliant, testing is planned but not complete as of this listing, so California customers should confirm current status before installing on a smog-tested vehicle.
Product Specs & Install Notes
- Up to 14 HP and 14 lb-ft gain at the wheels, dyno-tested back-to-back against stock
- High-density polymer airbox with high-flow dry filter
- Smooth intake tube sized for the factory MAF sensor
- Patent-pending QuickSnap magnetic lid, tool-free filter access
- No tuning required on most trims, no check engine lights
The 6th gen 4Runner finally ditched the old V6 for a turbo four, and Toyota left some real airflow on the table with the factory intake. This pulls from the same fender-area opening the stock box uses, but routes it through a bigger airbox and a smoother tube built specifically for this engine's MAF sensor, no adapting a part meant for something else. That's where the 14 HP and torque gains come from, confirmed on the dyno, not just claimed.
Most installs take under an hour with basic hand tools. One thing worth knowing from an owner who's actually done it: budget a little extra time your first time through, especially getting the MAF harness clips off cleanly and routing everything (including winch wiring if you've got one) so it doesn't rub or bind once it's back together. Rushing the fitment is where people run into trouble, take your time and it goes in clean.
You'll also notice a real change in how the truck sounds, more turbo whistle and blow-off flutter under boost, though nowhere near as loud as the Trailhunter's factory snorkel. It's there when you want to hear it and fades into the background at cruise or with the windows down.
Real owners who've done this swap say the same thing: don't rush the MAF harness clips or your wiring routing on the first go. Take an extra ten minutes there and the install goes in clean. Skip that step and you'll be fighting rattles or a loose fit later.
