Why the Right Intake Makes All the Difference on the 2025+ 4Runner
With the 6th generation Toyota 4Runner (2025+), every component matters more than ever. Stricter emissions, advanced engine control, and greater expectations from off-road and street driving alike. A high-quality intake does more than increase airflow. It affects throttle response, intake air temps, engine sound, and even the emotional connection you have with your ride. The right intake will deliver power, reliability, and yes - satisfying turbo whistle or BOV flutter you love.

Why SXTH Element CPLT May Be the Best Pick for You
If you care about more than just peak numbers, SXTH Element CPLT delivers a package built for emotional satisfaction, not just statistics. Here are where you’ll notice the difference:
-
Sound & Feel: That turbo whistle and BOV flutter aren’t gimmicks — they change how you experience acceleration and boost transitions. If you love hearing your engine come alive, this intake gives you that without making everyday driving unpleasant.
-
Everyday Usability: While some intakes sound great under heavy load or high RPMs, they drone a lot at highway speeds or idle. SXTH balances those so cabin quiet is preserved most of the time.
-
Reliability and Fit: Designed specifically for the new 4Runner, no guesswork. Precision tube routing, appropriate sensor placements, filter access. Other brands sometimes adapt more generically or reuse parts meant for older models — which can cost you in fit, heat soak, or maintenance hassle.
-
Value in Gains + Experience: The performance gains are real, and paired with premium sound and a clean, dry filter system, they’re worth it. Compared to some other brands where you pay more but get less sound or more maintenance, SXTH gives a holistic upgrade.
Installation & Maintenance Tips
-
Install time: Expect about 1 hour with basic tools.
-
Filter cleaning: Dry filter makes it simple — blow out dust, replace when needed. No oil to reapply, so less risk of sensor contamination.
FAQ: Common Questions
Will I void my warranty?
Most likely, no. The CPLT intake is a bolt-on designed for fit and function. Unless your dealer proves the intake caused a failure, dealers typically cannot deny warranty solely for an intake swap. Always keep original intake in case you need to revert.
Do I need a tune after installing SXTH Element CPLT?
No, the design is compatible with stock tuning and MAF calibration. You’ll see gains without needing to remap or adjust engine management.
Will I get check engine lights (CELs)?
Not when properly installed. The system preserves sensor location and airflow characteristics sufficiently to avoid triggering airflow or MAF-related CELs.
How loud will it be?
More aggressive under acceleration and during boost transitions (turbo whistle and BOV flutter are notably present), but quiet and refined during steady cruise and idle. It’s built for a balance, not extreme noise all the time.
