So I was in the process of sanding the chrome off my CAI and painting it (high temp paint) and looked at the TB and it was nasty on the front. I could only imagine what it looked like on the back side and sure enough it was worse.

I didnt have any throttle response or idling issues so this was just maintenance and I guess at 65k, it needed it.

Anyway here are some before and after pics.

I used one can of brake cleaner BTW and one nylon and one brass detail brush.

 

yep thats how mine was and i only had 34k lol

 

The front looks a little dirtier than it should. Even with 65k, the front normally still looks fairly clean with a good filter in place... What kind of filter you running on your DIY CAI???

And yes, that's how my TB looked on the back after about 20k miles... lol, and I clean it every 20k... 3 times so far, always filthy...

 

Im running two 6" cones. I had 9s but they needed to be replaced and I couldnt find anymore so I bought these 6s but even now they need replacing. I dont like to wash filters out. Id rather replace them as needed.

 

last time i cleaned mine i went to napa and bought some tb cleaner and man that stuff works great....nice work weed your very detailed and thourough big ups

 

That thing was dirty. It always amazes me how fast the gunk builds up on there.

 

..it must feel nice to drive now...that was pretty dirty..

 

I also sprayed down in the intake and wiped out as much as I could but you know there is more down in there and I dont like that at all.
