How is the fitment on the kooks vs ARH 1 7/8 headers, both are priced about the same. Just curious if either have issues with spark plug wires touching.

Thanks

Or have issues hitting the frame, or in 4x4's the front driveshaft.

What vehicle is this for? My 1 7/8 ARHs fit perfect, no issues with plug wires or otherwise.

Another satisfied ARH customer. They fit flawlessly. The 1 7/8" primaries come close to the trans cooler lines on the pass side, but that's a relatively easy fix.

Good to hear.
I have a buddy that has installed several different sets and brands. he said the ARHs fit the best, he said Kooks sometimes have issues around the spark plugs...

They both fit close on the #3 cylinder but the Kooks are closer and actually made contact on my factory wire. Both were easy to get in and fit is good otherwise.

Thanks for the info on the Kooks, i have heard that from other people as well.

My kooks fit awesome. I went ahead and ordered a set of DEI boots for the plug wires.

I went through a few sets of plug wire before I found these and they work great with boot protectors. Nice tight fit and clean look.
