Post subject:  Air Intake

Has anyone modified the air intake on their CRD? I have heard of using the gas version setup, but has anyone tried a cone type filter with aluminum piping or something similar? Just curious what kind of gains could be had.

No one has done any good before and after dyno testing, if that's what you mean. I'm unwilling to go to the inferior filtering of non-paper elements and sand blast my turbo compressor blades.

Post subject:  Biggest gain will be intake noise

The argument for the 2002 Liberty 3.7L V6 air box has merit. Many have proven it by installing a Air Filter Restriction Gage and found that with the V-6 air box mod, air restriction is not an issue with our CRDs. Putting on a Cone shaped air filter will give the noise a big boost, but not the performance.
Engines with restricted air flow may benefit from the Cone shaped filter, but our CRDs don't need it.

I put a larger paper filter on mine ( http://liberty.eurekaboy.com/airintake.htm ), then tried the V6 air intake ( http://liberty.eurekaboy.com/v6airbox.htm ), then went back to the larger paper filter to see if I noticed any differences.

The V6 intake was an improvement over the factory intake and probably the best choice if you want the intake to look stock. I get better throttle response with the larger paper filter.

Much cleaner air, and probably cooler as well.

This is what is on the diesel wrangler I found.

The Egyptian Wrangler had something similar for the desel.
Other than a snorkel, what else is there?

Post subject:  conical filter

Someone on the other site who occasionally posts here has put a conical filter inside the factory airbox by extending the hose feeding into the airbox down into the conical filter. So that is another possibility.

I am currently making an intake out of the greenfilter brand twister housed cone filter, some 3" aluminum tubing, a spectre aluminum MAF housing, and a hard to find silicone elbow which adapts the 3" tubing to the turbo inlet. I am stalled right now because I need to make a mounting flange for the other sensor in the airbox (pressure sensor I think). I am having a difficult time finding a way to precisely cut a 3" diameter grove out of the flange I fabricated so it will hug the curve of the 3" tube and can be welded. I'll post some pics and part #s if you would like.
