Loren, just changed my plugs this weekend as per your sites instructions, thanks. By the way, it was not as easy a job as I thought especially when your back is on a creeper, the drivers side rear two plugs were a B$@#!*H!

Question though, I picked up my plugs from the dealership and they advised me to use plugs Bosch 14FGR6KQU and not the FGR6KQC that came with car per Porsches recommendation?

Anybody know the reason for the change in plugs? Incidently the differnece in price is a whopping $10.00/plug <img border="0" title="" alt="[Eek!]" src="eek.gif" /> instead of the $8.00/plug I was expecting to pay.

Interesting I was told to use the fgr6kqc as they replaced the others and are the newer and better plug for detonation problems etc. They did run about 10 bucks each and changing them was fun for me too!

Could they be wrong? That would toally suck if so!

Yup... I need to change my DIY page as Porsche has updated the parts list.
Beru 14FGR 6KQU (p/n 999 170 207 91) is the latest Porsche recommended plug. This is actually the 4th different plug they have used since the original 98 and 99 plugs were single electrode. Most likely just a heat range change this time.

Also, supposedly the new plugs are supposed to go 60,000 miles between changes rather than 30,000.

WHEW! Man... I am so glad I don't have to do that one again... like I said that was no fun and the 60K milage I will get out of them really makes me breath easier. Thanks Loren. Brakefluid change this weekend. Anyreccomendation on where I can get some ATE Gold and the Matrix pressure bleeder you refered to?

OH, I forgot, I should have also mentioned that even though the plugs have 60K on them I would reccommend a regular PM on the screws that hold the coil in as I found a few that were missing that had apparently backed themselves out.

14FGR6KQU is a Beru plug. FGR6KQC is Bosch - it it the one in the picture with 4 side electrodes. Both are heat range 6. Jeff

SPR

so are the new ones the ones with the 4 electodes? FGR6KQC ? Those are the ones I put in when I just did mine.

SPR

sorry the ones I put in are the new ones, just forgot which ones were listed on Loren's article.

CarreraFour

ToolPants, bothe FGR6KQC and 14FGR6KQU have four electodes. The only physical difference is I could see is 14FGR6KQU has a slightly larger electrode.

I thought Beru and Bosch are the same company. It is still a Bosch plug, right?

Tool Pants

Beru and Bosch are separate companies. All the Beru plugs I have seen were made in France. The coils on a 996 and Boxster are made by Beru. <a href="http://www.beru.com/english/home/index.php" target="_blank">http://www.beru.com/english/home/index.php</a>

I have a 1997 Boxster so the plugs you see in the picture, except for the 4 side electrode Bosch, are for a 1997-1999 Boxster. The 4 side electrode Bosch plug in the picture came out of a 996.

1997-1999 2.5 Boxster with 2 side electrode plugs are supposed to be replaced at 30k miles. When the 2.7 and 3.2 came out in 2000 Porsche put in 4 side electrode plugs and they are now changed at 60k miles. The 2.7 and 3.2 Boxster uses the same Bosch FGR6KQC plug used by a 996. Jeff

Jeff,

For the 996 (all non-turbo cars)... the Bosch FGR6KQC (p/n 999 170 204 91)has been replaced (in the current parts list) with the Beru 14FGR 6KQU (p/n 999 170 207 91).

This is also true for all MY00 and newer Boxsters.

Uh oh, now you guys have me nervous. I haven't changed my plugs yet but, I was planning to do it myself. I have seen Loren's DIY sight. But, can anyone offer any other tips, tricks or advice that would make it easier? I've changed plenty of plugs on other vehicles, but never on a 996. Thanks.

B-Man I could not find any quick tricks except a compact mirror that I stole from my wife's purse to lay on top of anything I could find to see the bolt on top of the coil. Then as you get to the rear plugs use two three inch extensions inserted one at a time on the spark plug socket to get the plug out instead of one six inch extension. As you unscrew the plug from the boss remove the first extension and put your rachet wrench on the second as soon as you are able. If you don't the ratchet wrench will be too close to the muffler bracing to get it off the extension (that is part of the problem if you use one 6inch extension, mine was further complicated by the fact that I have snap-on tools and I was unable to depress the button to get the ratchet off the extension- here is moment when cheap and simple tools are wished for!) I also found that the plastic hooked dental tools in my fire arms tool box were handy for pulling out the spark plug socket in case it get seperated from the extension.

On the pain-in-the-**** scale for something that should be relatively simple, this job was a good 7.5!
