Spulen Engineering produces go-fast parts for VW and Audi vehicles. With Spulen parts you get more efficient operation, so your tuned car shifts smoother, accelerates faster, and handles better.

Subtle changes add up: shorter throws, wider stance, adjustable suspension, cold air induction, free-flow intakes. Spulen addresses all these needs and more with such products as bolt-on manual transmission mods, dog bone mounts and inserts, turbo inlet and boost pipes, oxygen sensor extenders for test pipes, wheel spacers and bolts, blow off valve kits for MQB MK7 applications, and rear differential mounts for Audi vehicles.
