The N54 engine is no stranger to oil cooling problems, that’s why we recommend installing the MSL Oil Thermostat. The standard oil thermostat will reach around 120 degrees Celsius with a normal driving style. The MSL Oil Thermostat will open at a lower temperature than the standard oil thermostat (at 85 degrees Celsius) and will keep the temperature stable between 95 and 105 degrees Celsius. Installing the MSL thermostat ensures a cooler oil temperature which will result in more stable performance, but above all this improves the reliability of the engine. It is recommended to install the thermostat, especially for cars that are tuned.

Eliminate your squeaking accessory belt pulley and cracked drive belt with this upgraded accessory belt service kit! This kit includes the ECS Kevlar Reinforced Accessory Belt, tensioner assembly, and your idler pulley. ECS Tuning's Red Kevlar Accessory Belts are both an aesthetic improvement and a performance alternative to a traditional belt. Kevlar-reinforced belts experience less elongation over time minimizing the amount of belt adjustment needed as well as offering a higher shock and impact resistance compared to OEM-style belts. Refreshing the rollers and/or tensioners simultaneously is a great way to ensure all vital components of your drive belt system are functioning optimally for years to come!

2007-2010 E90/E92/E93 335i N54 Stage 1+ Performance Package
Peak Power Gain*: up to 103hp / 108ft-lbs
+ aFe Pro5R Dual Cone Intake
+ Wagner Front Mount Intercooler
+ Cobb AccessPort programmer

More power = more heat. It's easy to make more power one time but to continue making that power consistently requires careful planning and design. With the additional boost the air entering the engine is also warmer, making the intercooler more important than ever. In testing, the stock BMW intercooler was quickly overwhelmed and cannot keep the intake air cool enough. The engine computer recognizes that and dials back the boost. A more efficient intercooler will keep boost levels up, delivering consistently higher boost levels. The Stage 1+ package includes a Wagner Evo I plug and play intercooler upgrade. We get great feedback from our customers and technicians about the Wagner FMIC - it's a direct bolt in part using all of the factory piping and it offers 85% more surface area than the factory intercooler.

The aFe Dual Cone intake and Cobb Accessport programmer complete the Stage 1+ package. The larger surface area of the aFe cone filters allows more air to enter the engine - creating more power and torque, a richer engine sound, and better throttle response. The kit is supplied complete with aFe Pro5R filters, mounting shield, intake tubes, sealing materials, hardware, and install instructions. The torque increase and sound from the open intake from low-mid RPM is sensational.

The Cobb software tool puts multiple tuning stages in the palm of your hand. Our Stage 1+ package lines up with the Cobb Stage 1 tuning maps for an intake and FMIC (91 or 93+ octane fuel). Simply download the Stage 1+ map from the Cobb website, plug it in, and install. Select different maps for other upgrades, throttle settings, octane ratings, valet mode, or revert back to stock! If you're moving up in Stages simply download a new file from the Cobb website and update your AccessPort programmer! The AccessPort triples as a diagnostic tester/reader and a data logger. It's the most feature-packed programmer on the market today.

We have taken the guesswork out of choosing the best upgrades for the N54 engine. If you follow the upgrade path we have laid out you will have very satisfying and reliable results. The addition of the larger intercooler makes Stage 1 more enjoyable and won't let you down at the track or dragstrip. * Note that peak power gains are quoted remain the same as Stage 1 but the cooler intake air means there is less of a chance the engine computer will cut power from heatsoak.

This item fits the following BMWs:
2007-2010 E90 BMW 335i 335xi 335i xDrive - Sedan
2007-2010 E92 BMW 335i 335is* 335xi 335i xDrive - Coupe
2007-2010 E93 BMW 335i - Convertible
* 335is horsepower gains are lower due to the factory power boost in the "is" package
