Test results Carried out at AMD Essex rolling road.
Intercoolers being testing for ACT (Air Charge Temperature)
Results carried out on our BMW 135i
Standard BMW Intercooler (Stage 1 remap).
Average air temperature into intercooler: 115 degrees
Average air temp out of intercooler: 69 degrees
That's an average 49 degree drop, but anything over 50 degrees engine intake temperature is not good for the engine.
AIRTEC Intercooler (Stage 1 remap)
Average air temp into Intercooler. 84 degrees
Average air temp out of Intercooler. 36 degrees
Airtec intercooler was seeing an average of 36 degrees with an increase of around 17bhp.
The test shows with a basic Stage 1 remap, you can gain power with just having a Airtec intercooler.
With having an AIRTEC intercooler fitted and keeping air temperatures down means a proven increase in power.
This intercooler will fit the following models:
E90 Saloon
E92 Coupe
E93 Convertible
E91 Estate
E82
E88
