BMW M42/M44 Complete ITB Kit for E30/36

Enhance the performance of your BMW 318is with this complete ITB (Individual Throttle Body) kit, with variations tailored specifically for the E30 or E36 chassis to maximize fit and function. This kit is designed to integrate seamlessly with the E36’s engine bay, ensuring perfect compatibility with the chassis and engine combination. The E30 variation is made with a slightly higher angle to clear the brake booster, this kit is tailored specifically for the E30—not just the engine.

The kit includes everything required for installation: throttle cable attachment and linkage mechanism, idle valve adapters for M44 and M42 engines, a vacuum accumulator with fittings, and hose tails for both left-hand and right-hand drive vehicles. Proven on the dyno, this kit can deliver up to a 20% power increase using the factory ECU, with the potential for over 30% gains when paired with a standalone ECU. Generally, no additional tuning is needed, but tuning can provide further gains.

All kits come with polished silver trumpets, and for those seeking added airflow performance, an optional carbon fibre plenum in a glossy finish is available.
