MTC Motorsport BMW N54 135i 335i Stepped Front Mount Intercooler, also fits many other models. We have engineered these intercoolers using a bar and plate core matched to our flowed cast end tanks. This is the most efficient way to keep the intake temperatures low. The MTC intercooler features massive 5 competition core with flowed cast end tanks and increased the surface area. Ability to deal with over 600bhp. This intercooler provides near 100% more volume and 100% more surface area than the standard intercooler. The intercooler is a direct fit and there are some great videos on YouTube to follow. However, professional installation is recommended and should take approximately 1-2 hours. We have tested our intercoolers on a few vehicles and found they have absolutely fantastic results. The IAT compared to the standard intercooler are reduced massively which means you get consistent increased performance. The standard intercooler and the MTC intercooler both had intercooler intake temperatures of between 135-140 degrees through 5 runs on the road. At the other side of the intercooler into the engine the standard intercooler temps were between 75-80 degrees whereas the MTC intercooler temperatures were in the high 20’s over all 5 runs. We would go as far as to say this is the best intercooler on the market for these models.
