Bosch 24lb Fuel Injector Set for Tuned S50 / S52
Premium quality 24lb Bosch fuel injectors for custom tuned E36 M3 6 cylinder engines (S50 & S52)
If you're pushing the power envelope with your E36 M3 race car (S50, S52) - anything over 225whp - you're very likely in need of getting more fuel into the combustion chamber. Stock 1995 injectors were shared with the 325i and run out of fuel very quickly. The S52 injectors had a bit more ceiling but still run out of flow with simple bolt-ons like software and HFM. The Bosch 24lb* injector has been the go-to solution for S50/S52 race engines needing more fuel flow**.
This is a set of 6 factory rebuilt fuel injectors, perfectly remanufactured by Bosch and tested for ideal flow. These should NOT be confused with aftermarket reman injectors, which vary wildly in quality. These are the real-deal Bosch 24lb everyone talks about.
Upgrading to 24# Bosch injectors is pretty common on S50/S52 powered BMWs with added custom tuning. But beware - There are other "24 pound" injectors out there that don't flow at the correct rate, or don't match the earlier "metal body" fuel injectors some of these tunes were originally created for. If you want the consistent and expected flow rate on a tuned 3.0 or 3.2 liter, these pink Bosch EV6 plastic body fuel injectors are the only ones on the market you should trust with your tuning. The original metal body EV1 Bosch injectors have not been available for many years, making the rebuilt examples and aftermarket copies very questionable. These are the only BMW 24 pound injectors we recommend to replace the original Bosch EV1, or for any more modern tuning expecting the EV6 style.
