This high-quality, performance engineered diverter valve is designed to replace the factory plastic diverter valve, which is a common source of boost leaks. Unlike the OEM valves, which use a fragile rubber diaphragm that is prone to failure, the 034Motorsport Diverter Valve features a high-performance spring and piston design. This means that the valve lasts much longer, and is capable of handling increased boost pressure.

The 034Motorsport Bypass Valve is fully serviceable and rebuildable.

This complete silicone hose kit is designed to replace all of the crumbling plastic and rubber awfulness that is the factory breather hose system. Fits transverse 1.8T cars with engine codes AWV, AWW, and AWP through the 2002 model year.

Fully reinforced silicone breather hose is designed to replace the crumbling, leaking OEM rubber part. This hose runs from the bottom of the intake manifold to the check valve attached to the lower block breather hose.

Replaces OEM part number 06A 103 221BK.

Phenolic intake manifold spacer for the 1.8T, 10mm thick, includes 2 OE gaskets and longer hardware for an easy, quick install.

Fully reinforced silicone 1.8T lower block breather hose to replace the crumbling factory plastic and rubber lower breather hoses. This hose fits numerous transverse engine configurations among Volkswagens and Audis.

Reinforced silicone breather hose for Mk4 1.8T, runs from the lower block breather hose to the small nipple on the valve cover breather port.

034Motorsport's high-quality silicone PRV (Pressure Regulating Valve) Pipe to Turbo Inlet Hose for the MkIV Volkswagen Golf/Jetta/New Beetle & 8N Audi TT 1.8T is a direct replacement for the factory hose. The OE breather hose is a very common point of failure, and almost always rips when removing the turbo inlet hose or PRV. Constructed from 4-ply high-temperature automotive grade silicone, this will not crumble apart or rip like the factory rubber hose.

Replaces 06A 103 221 BR.

Fully reinforced silicone transverse 1.8T valve cover breather hose to replace the crumbling rubber unit. 

This hose replaces the stock valve cover breather y-hose on Early AWP (1999-2002) MkIV Volkswagen 1.8T models. Early cars have a 20mm nipple on the valve cover, while late cars have a 25mm nipple.

Phenolic intake manifold spacer for the 1.8T, 10mm thick, includes 2 OE gaskets and longer hardware for an easy, quick install.

The VW and Audi 1.8T engine, due to the proximity of the coils on the valve cover near the exhaust, suffer from harness degredation. Our harness solution uses automotive grade wiring and harness building materials designed to withstand years of abuse and offer an affordable, elegant solution.

A blow off or recirculation valve (be it piston, diaphragm or OEM) will be activated by vacuum or electricity, and is designed to improve the drivability of your vehicle giving you maximum power when you want it. All types rely on an internal spring in order to maintain a seal so that you have boost pressure when it is needed - If the spring is too weak, you lose power.
