Cabin Air Filter Mod
Well it was discussed a whole bunch a while back, and I've finally done it. The little side project I've been working on during the puttstick install is adding a cabin air filter. Its still sitting on a bench with the epoxy curing all the way, but Friday after work it'll take 15 minutes to pop in and button back up. I'll get pictures of the finished product for you guys up then too.
The process I used was pretty simple. I took out the black plastic piece with the metal mesh on it that covers up the opening under the cowl that then leads to the intake for the HVAC system. I took that with me to Advance Auto and picked through every box of cabin air filter they had and happened to find something almost perfect. It was a box that had two filters that were just about the right size for each half of our opening.
Then I went to the hardware store and picked through tons of crap, finally finding exactly what I'd hoped for. I found a ceiling tile frame piece made of plastic that was again almost exactly the right size. I then used an 8' piece of that for less than 4 bucks and cut it up to build my housing for the air filters. I also trimmed up some excess from the air filters to make the top and bottom surface flush with the actual filter media to make it fit perfectly in my frame, then plastic epoxied it all together. I thought about making it easier to change the filters, but decided it was easier just to epoxy the end frame pieces on and use a razor to cut them off for a filter change down the road.
This got bumped up my to do list a bunch because I wanted to get it done before doing my EVAP replacement. I don't know if it'll make a difference at all, but I'm hoping that by actually filtering the incoming air I can make my new EVAP survive a bit better.
My car won't ever be done because I'm insane. That is all.
