someone told me a while back that you can get brand new plugs from autozone or checker that fit on the S4 n/a low impedance injector. it was made by bosch i believe and they gave me a part number but i dont have the paper anymore. can anyone tell me what the part number is?

also, will an FD differential fit inside an S4 or S5 n/a differential housing??

 

Summit Racing has them, just look up fuel injector plugs. They come 8 to a pack, so they're also good for replacing worn out BAC and water pump housing plugs.

I haven't heard about the FD Diff into an NA housing - but the Miata's Torsen unit apparently will. It's been done before by a girl in the 2nd Gen archives. I don't remember who, but I think it was first page, and she said it's awesome, like a totally different car now in terms of pull.

 

ah, nice thank you for the information

my buddy just put an FD torsen unit in his TII differential housing, but i thought n/a diff's were slightly different, so i didnt want to buy one and it not work.

 

I'm not 100%, but I'm pretty sure there's a difference between the N/A and TII diffs in terms of the amount of space side to side and the length of the pinion gear. The bonus for N/A's is that Miatas are fricking EVERYWHERE so the Miata torsen unit should be easy to find - especially compared to FD's.

 

ah cool, i'll see about a miata one, thanks

 

If you don't need then right now, check out eBay...


No, wrong size.
As someone already mentioned, you need to find one off a Miata.

Yep, miatas fit the NAs, FD's fit turbos for diffs.
As for the injector clips, yes you can get them from autozone. The part number was posted by Karak. Try searching for posts by Karack that inlude "injector clip" or something like that. I believe the post was 2+ years ago, maybe a little less.
Edit: it looks like it wasn't him, since I can't find it. If I come across it, I'll let you know.

 

ok cool, the only thing that comes up on summit when i search injector plugs, or fuel injector plugs is a 4 back of bosch something, with no description or picture.

 

Change plug to connector - you'd think they'd think of that at Summit
