I have an E30 325i and the only performance item I have is the Signature Motoring performance CAI for about $150. The performance kit adds around 9HP on the dyno, sounds freaking great, and installs in under 30 minutes. Highly recommended.
-Avg 9 HP increase
-Lifetime filter
-SOUND AWESOME
-30 min. install time
Aside from the power gain, the SOUND is amazing at higher RPM but sounds normal in regular driving. I’m thinking about added high-flow exhaust next.
My daily driver is E46 328i and E30 325i weekends. 325i is more responsive with Signature Motoring performance (CAI) intake kit. Installed it myself in under half hour. HP increase on the 325i is about 9.5HP for a cost of $170 or around $19 per HP gain. Best 1st performance mod to do. Other application data:
Sounds good.Do you have a Scorpion exhaust system? Is there much difference between a tuned 325i and a 327i? I have a twin dtm on my 325i Sport.Gives it a real blast when you stamp on the pedal.
