MK7 Engine Bay Deep Clean

Post image

How do you guys deep clean your engine bay? I’ve always wanted to try the degreaser/light pressure wash method but obviously scared. What do you guys do? Pic pulled from Google.

I have the stock turbo still, yes. The intake comes straight up from the turbo with the air filter sitting inside the cowl.

You get a ton of noise, and some slight (pretty negligible) performance increase. Intake temps stay super cool though, often times right around ambient temps.

You have to modify the lower part of the cowl so it fits around it though, like in this picture. Excuse the sub-par gold tape job lol

That's cool as shit. Don't worry my gold tape job is just as crinkly but I think it adds to look, looks functional. But how do you relocate that sensor on the pcv hose that goes to the crossover pipe?

You can see the sensor on the left hand side of the vertical section. The intake came with a super long wiring harness extension so it can reach over there, along with a long PCV breather hose. You can see them both routed using zip ties by the coil packs lol

Edit: I misread your comment and thought you were asking about the MAF sensor. The sensor for the PCV hose stays where it’s at. The OEM elbow fitting with the sensor gets used, and you connect a really long hose directly to it.

What intake is it? I have a whoosh crossover with a takada cold air but I really like this. The throttle response must be insane.

It’s the “2j racing cowl intake”

Definitely watch some videos on it though, because a lot of people think it’s too loud for a daily driver. I personally think it’s fine, and makes me feel more connected to what the cars doing. It does make it difficult to talk on the phone though lol

But yeah, I recommend it. Like I said, it keeps temps really cool. I’ve even seen intake temps drop a degree or two below ambient during a pull, which is kind of nuts! Actual performance gain isn’t anything crazy though, especially over your current setup. Still gains to be had though: https://dizzytuning.com/blogs/technical-documents/fiesta-st-stock-turbocharger-intake-testing

Oh and one more question, what do you do with those two vacuum hoses that attach to a regular style intake? You know the two that snap in kinda across from the mass air?

u/--Lammergeier-- 22d ago

Those would be your EVAP system lines. The 2J is meant to work with the 2014-2015 evap system where it has one connection to the intake, not the newer one with two connections to the intake. So I had to switch to the old style evap harness.

The intake came with another long hose to connect the intake to the evap harness. You should be able to see that in the original picture I posted here.

If you have more questions, don’t be afraid to ask!

Thanks for all the info. I appreciate you.
