I even had dust with the stock air box/filter! Honestly, it's probably just my environment. This pic is of the top "clean" side of the OEM air box, post filter.
Update to the above! I may have spoken too soon. Here is the inside of my intake pipe and MAF housing after using the AEM Dryflow for about 2-3k miles.
The amount of dust doesn't concern me much, but moreso the size of the particles that made it through. Keep in mind all intake components were...
I think this topic is more relevant in the diesel community considering the conditions they operate in, and like you said the crazy amount of air flow turbo diesels flow.
Yeah the reusable oiled cotton filters suck in terms of filtration compared to paper. But as I said above my UOA's have been excellent using the PRL HVI, and I do live in a pretty dusty environment.
As for turbo wear, a lot of the turbo diesel guys have discussed it at length on various forums...
I believe any particles that get through an air filter will be too small to be caught by an oil filter, but don't quote me on that.
My main concern with air filtration is mostly top end/turbo wear rather than bottom end wear. I don't think turbo or valve train wear would be caught by a UOA.
What intake/air filter do you run? It's been said that the best oil filter is your engine air filter. At least in terms of keeping dirt out of the oil.
That said, I've been using OEM oil filters and the PRL intake for about 15k miles and all my UOA's have come back clean with minimal wear/silicon.
I did ask John about it and he said it's more than likely false knock or poor fuel quality. And no, I didn't feel it while driving.
I'm also in the process of doing a custom E tune with another tuner, and the custom tune has 0 knock retard across the board no matter what I do. Although the...
Yes, I've been doing logs. Max boost I get when tuned is about 20 psi and holds 18 all the way to redline.
I'm not sure how accurate the hondata app is, but on the stock tune it peaked at 250 horsepower, and with the tune, 305. Not nearly as much power as a sea level car, but 50 more...
Thank you! I see like max 18 psi which quickly tapers down to 13-14 on the stock tune. Hoping the phearable tune is able to hold boost better throughout the rev range without over spinning the turbo
Just want to add that the AEM Dryflow is a great option for the HVI. I was concerned about sealing as well, but the intake tract is always very clean after running the Dryflow. Even the rubber flange was spotless so you can tell it's sealing.
The same can't be said for the PRL filter. I would...
Ended up not getting jailbroken. The hondata guys decided to do the event early without notifying anyone so I drove 4 hours for nothing haha. I'll be taking this as a sign and probably won't be tuning it for the foreseeable future. I was on the fence anyways
