• Reset the ECU after installation to allow adaptation to increased airflow

 

Frequently Asked Questions

Q: Does this kit include the MAF sensor and housing?
A: This system does not include the MAF sensor. You must use the MAF sensor from your 3.4L donor vehicle, which connects directly to the intake tube.  The MAF sensor housing is available for '99-'04 years.

Q: Will this work with both early and late 5VZ-FE engines?
A: Yes, this intake system works with all model years of 5VZ-FE engines. However, MAF sensor wiring may require adaptation depending on your specific donor and recipient vehicle combination.

Q: How much performance gain can I expect?
A: Users typically report improved throttle response, especially in the low-to-mid RPM range, along with enhanced intake sound. Power gains vary,  but most experience noticeably better engine breathing compared to restrictive factory systems.

Common Symptoms of Restrictive Factory Intake Systems

• Sluggish throttle response, especially during initial acceleration
• Reduced airflow, causing the engine to work harder at higher RPMs
• Muffled intake sound is limiting audible feedback from engine performance
• Restrictive airbox design limiting cold air access in the engine bay
• Difficulty routing factory intake components in swapped vehicle configurations
