Not at all Ironman. There are a few key steps that they don't mention in the instructions tho, which I thought was weird. And I did have one bolt and two washers left over. The trickiest part is trying to slide the rubber gasket onto the heat shield (I used a rubber friendly silicone spray lubricant to assist me). There is also a bracket that you need to remove one valve cover bolt to install and what they dont say is that there is a hose bracket that is beside it that just pulls out of the valve cover, and is reinstalled thru said bracket. Other than that it's just following instructions. It does seem to take a while, over an hour, which is a bit more than a lot of them I think but it is pretty crowded under there. You sure get rid of a lot of it tho when you put in the K&N. I also installed the H13 SilverStar headlight bulbs but didn't get a real chance to try them out last night. I was hoping to be able to get the SilverStar Ultra's but I phoned Sylvania's hotline last week and the rep said that even tho they have an email saying they are going into production this year, they are probably still about six months away.
