I'd test one for you'all in sunny fla. I'm using the UPR Dual right now, But I wouldn't mind doing a comparison for 10 or 20k miles, I've had the UPR on there for about 50k now, it seems ok.(truck has 57k) I do like your mounting better though (looks more professional).

Thanks for reaching out! We'd need the vehicle in-house for a couple days, so we're looking to find somebody local. But if we do need another test vehicle, I'll keep you in mind!

Thanks again,

If you didn't need it for a couple of days, I might have been interested as I'm only 30 minutes away. Can't be without my truck and am not keen on leaving in someone else's hands.

Mishimoto

@Jim10517 We could probably get what we need in a day while you wait, but would you be able to use a rental car (paid for by us) if we did need it for more than a day? Our engineers and project managers treat every vehicle like their own so your truck would be in good hands and left in our locked and monitored shop overnight. This will also be a pretty non-invasive process mostly just requiring the removal of the engine cover and PCV lines.

Please let me know if you'd be interested. Thanks!

Sounds like you are trying to increase your test vehicle sample size more than ONE. Will you cover any warranty issues that Ford won't cover?

Mishimoto

Hi Takeda,

According to the Magnuson–Moss Warranty Act, any manufacturer supplying a warranty on a vehicle must be able to prove that any issue normally covered under that warranty is the direct result of the aftermarket part in order to deny warranty coverage.

It's very unlikely that a catch can would cause any issues that would require warranty work. If it were the case that our product caused an issue (such as the CEL we saw and corrected in the R&D of the 3.5L catch can), we would do everything in our power to make sure it was addressed for any customers experiencing the issue.

Thanks,

-Steve

Takeda

You didn't answer my question! If you install a catch can, and Ford voids the warranty, will you cover the cost of the warranty issue?

That is more a Ford and legality issue than it is something Mishimoto can respond to.

I put a catch can on my 2015 3.5 Ecoboost at about 4,000 miles. Forgot the kind, but when I change oil every 5,000 miles, it drains about 6 tablespoons I reckon. It was a high dollar thingamajig! I really have no idea if these things help at all. Two old boys with Ecoboosts totally stock, one has over 340,000 miles, the other last I saw was over 365,000 miles, nary a problem with stock Ecoboosts. I don't know. But must be something, otherwise why did Ford decide to put regular injection as well as direct from 2017 engines forward...

Oh, hey, if y'all need another '15, mine is available.

Ford added port injection for increased torque at low RPM. The mechanical high pressure fuel pump for DI has volume issues at low rpms:

This is an interesting statement in this article:

Dowding and his Ford engineering colleague Stephen Russ stress that carbon deposits on tailpipes and intake valves have never been an issue in their DI engines.
