Why bore out I hear you putt putt around

The whole idea for that placement is to get cooler outside air as opposed to the hot air under the hood. Ram air effect would be nice but it is more than the engine can handle anyways. The other important function is that the cold air intake be behind that plate in the grill to shield it from water ingestion during rain or water crossings.

Thanks, tj. I also have a cold air intake... It just seems like the grille is completely blocking the airflow that I might be able to benefit from. Just trying to improve the engine efficiency if possible. I'm probably on the road to a bored out throttle body in the future to fulfill my needs.

I ran a K&N back in early 05, tested it for about 15,000 miles
after cleaning everything of dirt and grime in the intake and installing the stock box and paper filter got better mileage, ran smoother, Oh and the hose up to the grill.
Funny Jeep did that to the KKs
Yes knew how to clean and oil them, ran them on the Harleys and 4 or 5 other vehicles
Never again after reading a lot of info since then

The one time I tried the oiled air filter, it started coating the inner walls of the air intake and the IAT sensor with a fine brown film of oil mixed with fine talc like dust that is not filtered out by the "performance" filter until it gets more clogged up.
That was the factory oil job, not the oft cited consumer over-oiling.

I've since used the AEM dryflow in my Rubicon and Megacab diesel with much better results. Filtration-wise, that is.
Horse-pressure increases are negligable. I even Dyno-ed my diesel before and after and the new intake,air horn, and muffler delete gave a measly 6 hp . I think I got more from installing an SRT10 hood .
