Roush CAI Leak

[Oscar6790]

Any small leak prone areas in the Roush CAI for gen 3?
Have a gen 3 with wrench light and no code, guessing is a very small leak in the intake tube or filter itself. Already replaced the MAF and that wasn't the problem. Or any tips on how to diagnose and find a small vacuum leak

is the car tuned? Roush CAI without sleeve will throw that wrench light, as tune is required. With sleeve, it will work on the stock motor.

It's not tuned from what I know but could be since the sleeve is on and still throws that wrench and no code. It also rough idles from time to time leading me to believe it may actually have the vacuum leak in the air intake

Smoke test will find a vacuum leak. DIY smoke generators are all over YouTube.
