Air filter threads are almost as bad as oil threads.....

Yes but not even close to 'tick' threads

I’m with the stock filter team, but i love those roush clear covers. I’m about to buy a set just for the covers.

Looks good, but $550 for a pair of filters and peek-a-boo filter covers seems a bit steep, unless there is more to the kit that I missed.

@Tripower .... truth be told I bought it for the looks BUT after a couple of conversations with Roush customer care and after reading some information they recommended I realized their air filters were IMO way better than most available. I believe AFE makes a custom version for Roush (like Sears used to offer custom versions of appliances under their Kenmore line that were made to enhanced specs for Sears). Totally subjective, but I feel my 2024 GT idles smoother and sounds better under acceleration. Before installing I cleaned the air intake runners upstream of the OEM paper filters - really, really thoroughly - as a test. I installed the Roush. After 500 km and some cottage road driving (dusty) I pulled the Roush filters and there was no dust at all upstream from them. I did this at 1500Km and 3000Km. They ARE effective. They did trap a lot of dust, a few wasps etc. I tapped them on a clean sheet of paper and a lot of debris came out. But - not enough IMO to wash them. I used a shop vac to clean them. They are totally washable (warm water and a mild "neutral soap" like Meguair's or Johnson's baby soap) let them dry thoroughly and reinstall. I actually bought an extra set of sir filters so I could just swap them out to let the washed set dry completely. Bought for looks super impressed with performance. My contact information with Roush Performance was: c/o Sarah R - Senior Agent Customer experience - [email protected] or 1-800-597-6874. Of course the products can be bought, directly, on line at Roush. BTW IMO they are very, very well constructed and very effectively made, big time quality.

Mehhh, I went with the Steeda Pro Flow Air Filters and change them out every 3-6 months depending on how much I am driving. Bought a 2nd pair so when I replace the ones in current use, I can let the washed ones dry for an extended period. Always have a pair on standby. Cost wasn’t a concern. YMMV …

Agreed. I've run Steeda filters literally since I can remember. Have a second set, wash them by soaking in warm water with their cleaning solution. Put them in the sun on shop towels for a day. Conservatively coat each pleat with new oil. Next put them on a shop towel below and on top, first with the small end down, then flip them with the small end up for a day on each end. Gently rub the rubber ends with a cloth in mineral spirits. I do this process about every 10K miles, I always have a clean set on the shelf. I've never had a spec of oil in the intake or MAF.

I agree that the double filters and throttle bodies are likely beyond the needs of a 307 cubic inch engine, so OEM filters are likely adequate on the S650. Interestingly, the K&N CAI actually hurts overall HP on a stock 5.0 Coyote. Likely the smaller inside diameter of the air tubes between the MAFs and the TBs on the K&N kits.

I'd really consider an oil vapor recovery system on a 12:1 compression 5.0. Really helps keep the intake tract and especially the intake valves clean.
