Any one using the RS air box lid? If so, I have a 2014 ST. Got just the RS lid from EBAY, but having problems with fitment. Anyone else have any fitment issues? It's almost like the RS lid is a hair smaller than the ST airbox. Thank you.

it's supposed to be a direct fit.

Ok. Messed with it for 20 mins. Got it on there, just didn't look or feel like it fit on there as good as the original.

How much did you pay for just the lid?

Are you sure it was oem ford rs lid? Post a pic. I know the lid came with different size bolts (7mm) than the ST (8mm) but the lowers are supposed to be identical. There could be a slight difference in tolerances since the rs box is made in Europe and imported here.

Paper works says OEM. What I found odd though, inside the lid it has part number, then under that, says Focus RS, then under that, says Focus ST. Sucks cause there's a guy ( in the UK I think) that 3D prints the RS lid, but it has the ST logo instead of RS. I didn't buy because I was worried about fitment issues. I paid $77 for just the lid, but didn't mind paying more for OEM, but still having fitment issues?

My guess is it's just your filter. I have a green filter and I've struggled to put my OEM air box lid on the few times I've had it off. The bolt holes never seem to want to line up unless it's absolutely perfect.

Why didn't you buy from a ford parts place like Tasca or bear nation it would be $65 for the complete box with a filter?

I didn't want to have extra parts laying around. Wife already complains about all the car parts. I still have parts from my two previous vehicles and parts for my current GMC Jimmy project. I have a problem hoarding car parts.

You could of sold the lower half and filter to a n/a 2.0 se/sel/ti owner

Maybe, but SE owners usually buy the whole part and swap. I paid, Tasca, $69 and change for mine shipped to NY, but depending on shipping it could cost much more.

I used the blank file to replace the insert on the RS lid and no complaints, found a company to print it on cloudcraft. $16ish shipped



No one makes the entire top cover that i am aware of.

Is the insert removable or did you have to cut it? Is it glued down?

its one piece, you cut out in pieces :)

I just used some snips to get the bulk of it out.



Then i used a rotary grinding bit to smooth down the rest. I just followed the lines from the bottom and just kept going until they match the insert i had printed. The insert fit snugly when i was done, i didnt even bother epoxying it in since it fit so tight

Sounds too easy! Got a 3D printer too :) Have you had any issues with the filament melting?

Just research what you are printing it with first. I had mine printed in PETG, Google says to set your working temps to above 235c when printing PETG. Knock on wood, my under the hood temps wont reach its melting point ;). With the RS design with that gasket that seals with the hood, its shielded from the direct engine bay heat anyways. PETG is also has good chemical/acidic/alkalic/water resistance, so should be just fine under the hood.
