Spark Plugs
Anyone have a good recommendation for a good brand of aftermarket spark plugs/ coils for my Porsche Boxster 987? So many choices, just don't have a desire to go to a dealer for them as it's a DIY project.
Thanks! CJ |
Go with the stock Bosch, there’s really no better solution and some brands can cause issues. |
Agree to stick to Bosch. It is not a lot of cash to get the same part as OEM. If I recall, there are some that are not Porsche stamped or a slightly different PN that are cheaper Bosch and the same thing.

+1 for Bosche. Buy through FCP Euro for the lifetime warranty and free shipping. |
For as often as I'm gonna replace them, I bought the Porsche plugs and Coil Packs from Suncoast. Done and done. YMMV.
|
I like Pelican, they have the exact Porsche part and the part that are made by the same manufacturer that Porsche uses on their website.
|
Ends up that I only need coils. Plugs were replaced 3,000 miles ago by previous owner. Still recommend Bosch coils? Beru is stock so I could go with those but trying to find the cheaper (decent) option.

Can't speak to the aftermarket question as I bought all Porsche stuff from Suncoast when I did mine, but...
Mind the bolts... original had different mounting thickness of the part, hence different bolts (length and potentially head). Know which ones are required for the new coils and be sure they are either included or you acquire them with your purchase. Ditto on knowing which bolt heads are coming out and which are going in. Else, you'll be making an emergency run to Harbor Freight or the like to acquire some fancy sockets. Frankly, it sounds more intimidating than it actually is. Hoping you'll learn from my, ahem, experience. Good luck! |
Folks, what is the recommended plugs replacement interval?
|
From the schedule I've seen for Boxster/Cayman (987) (2005-07)...
Additional maintenance for spark plugs Labor operation 03 81 00 .. (Except Turbo) Replace spark plugs every 60,000 miles (90,000 km) or every 4 years |
987.2 (9A1) manual says 40K/4 years. Also there was some question whether the factory Bosch 99917013090 plugs were actually the more affordable Bosch FGR5NQE04...
I just opened a 99917013090 box and the plug has FGR5NQE04 stamped on the base, so don't pay the $15+ per plug at Porsche, get them for $5 at RM European |
My dealer wanted to charge $27 each for the OEM, I did go with the FGR5NQE04 that at exact same thing but less that $5 each, I ended up buying a new belt, plugs,carbon and air filter for less than the dealer wanted to charge.

I’m at 4 years, but less than 20k miles. Is there any part of the spark plug that degrades over time without being used? |
