Looking for an intercooler upgrade for my F30 335i. Stock intercooler heat soaks badly in summer. Options:
Which one offers the best cooling performance? Car is stage 2 making about 380hp.
Wagner Tuning EVO2 is the gold standard for N55 intercoolers. Massive core, great fitment, and it drops intake temps by 20-30C compared to stock. Its not cheap at around 800 EUR but its a one-time buy that supports any power level up to 600hp.
VRSF 7.5 inch intercooler is the best value option. About 500 EUR and performs within 5% of the Wagner. I have it on my stage 2 335i and intake temps stay under 40C even on hot days. The only downside is the install is a bit tighter than the Wagner.
