Frequently Asked Questions

Will this bolt to my factory intake manifold without modification?

Yes. This duct connects at factory mounting points—no drilling, welding, or custom fabrication needed. Test-fit before final tightening to confirm clearance at the intake trumpet.

Do I need to seal the joints where the duct meets the intake?

Depends on your setup. If you're running stock intake components, factory tolerances should handle it. For turbo or supercharger builds, you may want silicone sealant at connection points to prevent boost leaks—check your tuner's recommendation.

Can I reuse the intake filter element from my old airbox?

Not without adapter work. This duct uses a different filter mounting interface than the OEM airbox. You'll need a filter element sized and threaded for this intake's inlet—confirm diameter before ordering.
