Under bonnet photo of my m135i for 2 reasons:-
1. Installed OEM M4 strut tower re-inforcement rings - black parts on top of both suspension towers.
2. Been running this CAI for about last 2-3 weeks or so. Initial impressions are positive:-
- According to my jb4 app IAT's are a few degrees cooler compared to oem with drop in.
- Noise - slight increase in induction whoosh but not excessive
- Throttle response - did both throttle body and gearbox adaption resets once CAI fitted so difficult to say any gains before and after so. Feels good though - punchy when you get on it and stutter free on part throttle.
- Performance gains - car is fishing quick [JB4 stg 2 and BCS HFC DP] already so hard to gauge. Would need before and after dynos to show any numerical gains or losses.
- Looks - a splash of CF under the bonnet but this is low on my priority list as I don't drive around with the bonnet off !!!
