There's definitely a click when pushing the clutch in on my car. Been there as long as I've had the car.

Can an AlphaN tune optimized for a CSL airbox be used safely with the stock intake setup? Sold my Karb airbox and I can’t seem to find the pre-tune partial read.

I bought a new sunroof seal (54138218001) for aesthetic reasons and noticed it has a felt like look/feel to the outside of it, something I don't notice on the original seal on my car.
Is this normal for the sunroof seal to have this almost fabric feel and texture when new?

Also the sunroof seal came with 6 small torx screws yet I see no holes in the new seal, what are those guys for?

I believe the fuzziness is normal. My car has some fuzzy remaining, it appears to degrade/wear off over time. Glad to know this is a part that can be purchased.

Oh the torx screws are likely to secure the glass to the mechanism--you'll have to pull the glass to replace that seal. I've pulled the glass 2 or three times--the hard part is getting it level in my experience. If you determine a straightforward method please share.

Anyone know the part number for this hose? Having a hard time finding it in RealOEM




Edit: I think I found it. It's an assembly. I needed the quick disconnect. My Rogue Engineering strut tower brace is hitting up against this after installing new engine mounts last Fall. The engine is sitting up as high as it ever will...need to replace this quick disconnect.

Got another parts inquiry question. What is the part number for the rubber grommet that goes in this opening?

[toy4to]

Can anything be done for rear subframe reinforcement if the foam injection was done many, many years ago?

There are two different sets of c-clip/body nuts on the front support plate (3 each), that connect the under carriage diaper and other trim. One set is for short 10mm head screws and their other for 8mm screws. Anybody have the part numbers for each of these nuts? Mines are all stripped out and I can't find the PN. The initial parts I bought from FCP are incorrect. TIA!

Got my very first "service engine soon" light today after 5 years, it was a P0174 (bank 2 too lean). The code popped up on the interstate comming back from a track day.

I had a cheap OBD Bluetooth scanner/App and cleared the code while driving and it never came back driving over an hour home on the interstate and through town.

I have a CSL tune/MAP sensor, when the CSL airbox was put on 3 years back all new boots were used with OEM clamps, OEM CSL hoses were used, I even put new air rail orings in, new pre-cat O2 sensors were installed in the same time frame along with having my injectors sent out to RC for cleaning.

With the CSL tune in mind what else should I be checking for besides an air leak? I have a WB O2 sensor in bank 2, so I'll have to hook up testo and check that out sooner than later.

How old are the post-cat O2 sensors? I would INPA the see if you have any errors with O2 sensors and if you are getting proper readings for pre and post cat.

I literally just had one die in me and gave me a SES light. My cost was for fuel adaptation and it was a pre-cat O2 sensor that died.

Post cats have 72k on them but aren't aren't being read from.
I'll have to get it up in the air and check the O2 wires, but I seem to remember doing a pretty decent job making sure the O2 wiring was routed and fastened as to melt on the headers etc.
I suppose it's not out of the question a newer O2 sensor could be bad.
