Cheap performance is good. In one of my previous cars (1.9LZ3) I had a full Dinan CAI system complete with software and bored out throttle boy. It did very well but also cost an arm and a leg $900+.
Was it worth it, heck yes. Cool sound, much better throttle response, increase in upper rpm power.
When I got the 318 I was immediately looking to upgrade the air intake system. However little if any prebuilt systems were out there. After enough reserach I saw that some owners made their own CAI. Inspiration struck.
Heres the parts list:
Ebay K&N Cone filter with e30 adapter plate - $50
Vibrant* #2173 3" dia. 90 deg. aluminum elbow - $25
Vibrant* #2182 Blue 3"x3" Silicone Adapter Sleeve - $9
2 extra 3" hoseclamps - $2
* Vibrant parts are available through any Keystone supplied car parts stores
Heres what it looks like:
I decided on the 90deg. elbow to get the filter as far away as possible from the engine and fan wash. I also removed the plastic cover from behind the headlight to improve airflow.
How does it run, great. Under WOT it growls loudly. When crusing around, its barely noticeable. Throttle response is GREATLY improved and while I did notice a little bit of a low end power drop, its much faster in the upper rpm ranges.
Next on the DIY list is a heatshield.
