Hey guys,
Did a little intake testing to disprove the "hot air intake" myth. I had been planning to use video, etc, but figured a basic OBDII scan would better prove the point. Plus it was a lot easier to setup.
Test vehicle: 2008 BMW 135, JB3 1.1v, Code3 Intercooler, Riss ******* downpipes, 91 octane
Test: For each intake cruise for 5-10 min to stabilize IAT, and then a 40-100mph acceleration run monitoring air intake temperature. Each log includes ambient temperature as well as stabilized air intake temperature (~64 degrees F and ~77 degrees F respectively).
Result: As expected
PS. If your single filter looks like this (this one has ~20k miles), time to clean it with a K&N cleaning kit from Pep Boys!
