Hey guys, Thought I would do a little write up for the guys that are interested in these but a little skeptical about cutting into the hood on your zj. Maybe this will give you a little confidence.
Ordered in my genright hood louvers. Really like the quality of them and the packaging was top notch. I called them and had them in three days which is pretty impressive.
1'' painters tape
1/8 drill bit
4 1/2 grinder w/ cutoff wheel
sharpie for marking holes
Pop rivit gun
On to the cutting:
This is how I measured and got an idea of where my 14'' louvers will go. Marked the underside of the hood.
A picture of the under hood. You can get an idea of where the best to locate them is.
Using the 1'' tape to line up everything. You should get the idea from just checking the pics.
I had a pretty large box that i used under the hood to shield of sparks and drill filings.
First Cut is always the hardest. cut it with a 4 1/2 cut off wheel on the angle grinder. The lines turned out very straight and was happy with the result.
Both holes cut. YOu get the idea of what cooling benefits it will have.
Mounted. Used a pop rivit gun and an 1/8 drill bit. Pretty standard. I am happy with the look.
Initial impressions are about 7-8 degrees cooler on the thermostat. The heat billowing out of them is pretty good. I would imagine the vacuum that they create is pretty significant. The real test will be the next few weeks when luggin around on the trails.
