DIY Intake with NAPA Filter
I did this little install with the NAPA cone filter and a 4" section of 4" diameter stainless pipe I had laying around after my exhaust install. My concern is that the 4" in length pipe is too long and creating a funky curve on my intake tube. It wasn't super hard to get the filter in place or anything, I'm just seeing if anyone thinks I should go out of the way to get a 3" in length section of pipe. Attached is a photo of the install.
Also, I had what looked like oil in the intake tube when I removed the old box. Is there anything I should be concerned with here? It wasn't much but I'm not sure if there is anything I should be doing. I've read some stuff saying that this is normal some stuff saying otherwise. Any thoughts?
