Hey guys, I know the “cold air” intake argument revolving around the stock m20 box is well worn. Not trying to win anyone over here. Just wanted to share my little project.
I’m 100% in agreement that these cars are great in stock form. That being said, my car will never be original and or a show car. I bought it to enjoy, and introduce my youngest son to the car world. My particular example was a bit of a mess when I bought it, so as I’ve gone through various systems making things how they should be, I also enjoy making my car “my car”. Anyhow, so I am 100% deaf in my right ear and tone deaf in the left from an illness as a teen. So while I like engine sounds I dont always experience the results my mods provide to others. My wife purchased me a Supersprint cat back for Christmas, and although it changed the tone of the exhaust, and sounds very nice, the car is still pretty quiet. I’m keeping the cat, and I’m not ready for headers yet, so after researchIng and weighing things out I decided to do an open filter intake system.
I’ve been a mechanic for most of my adult life, and consider myself to be pretty good at what I do. What I don’t know about I do loads of research. Being that nobody trustworthy makes an intake for the m20 equipped cars, I just decided to do it myself. My goal was nothing more than to enhance induction noise, while not loosing power doing so. Any other attributes are lagniappe.
Cost for the project was about $220 and I’d say 6 hours of my time measuring, templating and fabricating, and add a couple days or weeks lol of searching the internet for materials and parts and deciding if I really wanted to do this.
List of what I used:
Redeyegarage m20/m42 intake adapter $70 shipped
(Ryan gave me some solid advice about my shielding material choice! Thanks again sir!)
AFE Magnum FLOW Pro 5R part 24-91013 $92 shipped
16x24” sheet of .062 5052 alum. Amazon $39 shipped
10’ 5/8 vertical bulb trim seal Amazon $15 shipped
I had the hardware on hand but it amounted to 5 15mm m6 bolts nuts and washers.
Some notes:
- To make this work with the filter I chose I did have to bend the factory AFM mount, but it’s still there and I’m 100% certain I can use it to remount the factory box if I chose to. If you go smaller with the filter the bend may not be needed.
- All I did was take a piece of cardboard the size of my aluminum sheet and cut and shape it to fit where I wanted it. Once that was completed I just transferred it to the aluminum.
- I cut the aluminum with a jig saw and a fine tooth metal blade. I used some cedar fence boards to back up the aluminum while cutting.
- I don’t have a metal brake, so I used c clamps and the fence boards again and a piece of 1/8 x 1” 90 degree aluminum stock to form the hard edges and bent most angles by hand and used a hammer against a hardwood board for the smaller flanges.
- After cutting I hit the edges on both sides with a file, then test fitted. I made a few clearance altercations for final fit and room for the bulb seal.
- I used the inner abs pump mount as a lower mount for the shield and drilled two holes through the fender well for mounting purposes as well.
I’ll quit yapping and show some pictures. I was only allowed to post 5 so I tried to show start to finish within the allowed upload cap.
Thanks for looking
