The holes didn't seem to match up the frame plus there is something in the way on other side of grill don't know if it's wrong one or I have to move something I gave up after three hours
x2 on the cleaning. My injen had dust and metal filings in the tube. Would hate to see that go in to your engine!The holes in the box for the bolts need to be slightly enlarged so they align with the holes in the wheel-well. This is a common thing needed.
The horn also needs to be relocated so the box will fit correctly. You can either push the horns under the headlight if they will fit or extend the wires and mount them between the grill and radiator like the 05 models have OEM.
There is also a condensor containor or something that is technically in the way of the ram air horn. It does cover up some of the area but what can you do, lol.
That is about it. Just make sure you clean the tube prior to installing it since it usually has some dust and plastic particles inside of it.
Honestly you would probably save a ton of money and skip most of the mods or you would loose a ton of money having to do mods over and over to find the one that is right for you.What would I do without club frontier thanks a lot guys will definatly try it tommorow
