This Integrated Engineering cold air intake replaces the restrictive factory airbox on the Audi B9/B9.5 A4 and A5 2.0T with a velocity-stack design and an oversized air filter, mounting to the factory airbox points with the stock rubber isolators.IE rates peak gains at roughly 10-20+ horsepower and torque on a tuned engine, with a cleaner-looking engine bay and a more aggressive turbo and induction sound as a side benefit.Important Compatibility InformationThis intake does not fit engines equipped with a MAF housing and sensor - verify your car's sensor setup before ordering.Construction Flow-optimized velocity stack Massive 5-inch diameter air filter Three-piece heat shielding plus an additional shield above the turbocharger Durable 3-ply silicone coupler Black powder-coated velocity stack and heat shield What's IncludedIntegrated Engineering cold air intakeProduct Specifications SKU: I00W IEINCK1 MPN: IEINCK1 Peak gains of roughly 10-20+ horsepower and torque on a tuned engine, per Integrated Engineering Fits the Audi B9/B9.5 A4 and A5 2.0T Frequently Asked QuestionsWill this fit my car if it has a MAF sensor?No, this intake is not designed for engines with a MAF housing and sensor. Confirm your setup, or contact your BMP Tuning rep, before ordering.Do I need a tune to see the horsepower gain?IE's peak gain figures are measured on a tuned engine - gains on a stock tune will be smaller.Does this reuse the factory mounting points?Yes, it bolts to the factory airbox mounts using the stock rubber isolators.
