Product Description

The K&N 57-0432 is a 57i Series Generation I performance induction kit engineered specifically for 2001-2008 Volkswagen New Beetle models powered by the L4-1.8L 20V turbocharged engine. Unlike a drop-in panel filter, this open-element kit completely replaces the restrictive factory airbox with a larger, free-breathing K&N oiled cotton gauze filter that connects directly to the throttle body via precision-fit adapters. The larger filter surface area allows significantly more airflow throughout the entire RPM range, improving throttle response and horsepower without requiring any engine tuning.

The 57-0432 is designed for maximum simplicity - the kit installs in approximately 60 minutes with basic hand tools and requires no modifications to the engine bay. The washable and reusable filter lasts up to 100,000 miles between cleanings, far outpacing standard paper panel filters. Backed by K&N's Million-Mile Limited Warranty, this induction kit is a straightforward, cost-effective performance upgrade for any 1.8T New Beetle owner outside of California emission-regulated states.
