I Was reading that and couple others and decided to go with a OEM one. At 30 PSI its leaking 5 PSI every 1 and half mins. Trying to decide if its even worth throwing a new one on. Truck has 680k.

Your not likely to see any fuel mileage gains enough to compensate replacing it based on that leak rate alone. Just be sure to fix any other leaks in the engine while your testing things so they are not compounded. had a guy here one time who had horrible fuel mileage ... we pressurized whole engine up and his air compressor head was blasting boost air from the turbo into his crank case. Sometimes you find the problems in the strangest of places.

Thanks i use a Smoke machine and put a trashbag behind the air filter and pressure the system normally. But i kinda had a feeling my CAC was leaking as i hear it when i left off the boost right now. Think ill just grab an OEM CAC and put it on. I tested the boots one by one and 1 was leaking and didn't find any leaks about 3 months ago on the intake system. I Did buy all new boots anyway and clamps. Fleetpride gave a decent deal on them so i said sure why not lol $70 for all the hoses and clamps
