Anyone have one yet? I ordered one and a JLT catch can yesterday. I'm not expecting much of a power increase, looking for more blower whine. I think JLT is the only company that has one at the moment.
I had a JLT intake on the Durango SRT, can't say I really noticed any difference but I figured it couldn't hurt. This one may not make any more power either but my wife and I really like the blower whine so that's the real reason we're using the JLT.
I'm late to the party but I just installed it and JLT's catch can on my DDHC last weekend. The supercharger whine increased significantly; I'm super happy with the result.
"Adding an Outerwears Pre-Filter will not have any significant reduction in airflow (independent lab test results available upon request). Most Performance air filters allow more air in than the engine can actually handle. In fact, an Outwears pre-filter keeps your primary filter cleaner for a longer period of time allowing your engine the ability to sustain its original airflow and horsepower for an extended amount of miles and time. Many of our customers claim they have also noticed an improvement in fuel efficiency. This may simply be attributed to the fact that they are keeping their air filter cleaner. "
The pre-filter, while being slightly restrictive, keeps dirt and particles OUT. While a clean new air filter will be better... drive it 500 miles and it will have bugs and sand in the element that you won't get with a pre-filtered air filter. So, IMO from what I've seen by owning one, when I take the pre-filter off, the actual filter underneath still looks completely unused.
