Sorry for bad sound and picture it is a self made on board system costs about 20€
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.
