It took about 6 hours but I took off the entire front plastic because I was doing the snorkel kit too. I Hak to look over the instructions a few times and then it was a breeze.Looks good. I have the same color quad. What was the hardest part? I looked at the instructions and I'm up in the air. How long did it take
The 2.5 inch hole will give a little extra wiggle room and get the hot hoses away from the plastic. I can only see the holes if I bend down to look under the rack, so far I am happy with my install.I'd say the rad kit to me 3-4 hrs because it was the first time I'd done one. I feel I could do it in about half that now. The snorkels took longer just because its more involved.
I cut my holes to a 2.5 inch I believe. I don't even see them in the hood.
