Airtec Motorsport BMW S55 Hot Side Boost Pipes are a direct replacement for the plastic OEM boost pipes, which are more restrictive and prone to cracking - especially with increased boost pressures from tuning. The pipes have been designed to improve the overall internal dimeter and flow of the original OEM pipes, which flatten considerably where they pass over the top of the engine.
The Airtec Motorsport replacement pipes are constructed from alloy, so they will not fail with higher boost pressures and maintain e a 57mm internal dimeter from the start to finish. Both pipes also feature a 1/8NPT port fitting suitable for a methanol injection set up, and the exterior of the pipes are finished in a subtle black powder coat.
