Wondering if I cut a hole for more air, on the passenger side will help any?



Just can't help to feel, the engine is not getting enough air from the driver side. Thoughts?

The wiper motor is in the driver side i dont think the filter is going to fit.most people use the driverside and keep the factory box and element

Why did you go driver side? Shouldn't make a difference, but paasenger side is more water resistant, but any where in the cowl gets plenty of air for what the 4.0 requires.

If u use 3 inch hole drilled in the cowl, it's really plenty for the 4.0. In fact 3 inch is minimum u need.

Running the stock air box to the cowl you get more than enough air. and with the in line air filter you should be fine.

I really don't think added holes anywhere will help air flow.

Have you ever seen the stock tj air box opening with the same motor!!!

And it works just fine.
