The K&N 57i induction kit for Audi TT Quattro 1.8L provides a vehicle-specific oversized air filter and adapters that replace the factory air box restriction to improve airflow throughout the RPM range. The washable, reusable filter increases service intervals and the kit comes with K&N's No-Hassle Lifetime Limited Warranty. Note that some emissions-controlled states prohibit 57i installations.
