Why Ours Sounds Better

Unlike many intakes that leave the restrictive factory turbo inlet in place, we highly recommend pairing ours with our upgraded Turbo Inlet. The factory inlet features an integrated sound resonator that restricts airflow and mutes turbo noise. Our larger, free-flowing metal inlet removes that restriction, allowing the turbo to breathe more freely for a noticeably louder spool, stronger induction sound, and even better performance.

Installation

The intake is a straightforward bolt-on upgrade. The turbo inlet is more involved due to its location, so professional installation is recommended.

Verified Fitment

Confirmed to fit these vehicles:

Fitment Note: Do not rely solely on the vehicle/year fitment shown above. Always review the full product description before ordering, as some parts may require a specific bumper, trim, package, body style, or other factory configuration such as an M Sport bumper. Aftermarket bumpers, conversions, previously modified vehicles, or non-factory body components may also affect fitment. If you are unsure whether a product will fit your vehicle, contact us directly before ordering and we’ll be happy to help verify compatibility.

Email support@buildbargain.com with your vehicle's year, model, trim, and any helpful photos. Our team can help confirm fitment before you order.
