Hey guys, I have some aluminum intake tubing sitting around in the shop and some red steel tubing up stairs. What firewall can I run the filter into? The driverside? If so, where and is there already a hole to run it threw? I am very interested in the inside fender mounting style. I gotta go to work but will be back in a few hours and can see stuff on my blackberry. Thanks in advance! I think i have a few rubber boots upstairs to to connect the pipes, I just hope there all a standard size. I figured aluminum under the hood and if i ran out I could use the steel tubing in the fender. As far as the noise, my buddy has a 2004 chevy truck with the 5.3 and his cold air intake makes alot of noise! lol Its sweet. Was kinda hoping for the same as I have a N/A setup.
