Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

I am about to change out the spark plugs on my year old 996 coupe. I went to the Autozone website and punched in my make/model/year and it gave me numerous options. Which one does anybody recommend??? http://www.autozone.com/servlet/UiBroker?UseCase=C001&UserAction=performSearch&Parameters=Auto+Store|~RE GULAR+PARTS+LOOK+UP|~SPARK+PLUG Cost is not an issue as long as it is worth it. If it matters - very spirited driving in the mtns 5-6x a year, otherwise just aggressive city driving thanks for any input! fo

POST 2Original post

I would go with the OEM plugs, just not worth pulling them out if its not running right.

POST 3Original post

Use the oem's but make sure to get the newer superceded part number They are a 4 point plug btw and no other non oem replacement is.

POST 4Original post

Are you doing the 30K service? Reason I ask is that plugs are not reccomended until then. Never hurts though to put in fresh ones at any time

POST 5 / ORIGINAL POSTEROriginal post

Only have 12K miles and car is just over a yr old - changing the plugs mostly as preventative maintenance........and cause I'm bored and like tinkering with the car

POST 6Original post

Pull the plugs and if they are dirty, replace. At your mileage, if they are soiled, your engine isn't running at the right AF ratio. I wouldn't bother with the plugs. If you are bored, replace the differential fluid or tranny fluid.

POST 8Original post

http://www.renntech.org/forums/index.php?showtopic=720 On your year Porsche says the plugs are good for 60,000 miles.

POST 9Original post

well I replaced mine at about 30k and I noticed a nice improvement in idle quality and smoothness. They were pretty used looking on the ceramic. No pits but an older grey color not brownish

POST 10Original post

I only mention this becasue I just hit 50k and am going to replace them again-. Also check your boots and coils when doing so- Be careful about the connector locks as they're easy to break also.

POST 11Original post

Go with Bosch plugs. I have worked on many cars in my life and whenever I use a non Bosch plug on a German car they always started to go bad after 10K miles. OE is Bosch. BTW the same happen when I used a Champion plug on a friends Toyota Celica, we ended up putting back Nippon Denso after 12K miles. The moral use a OE plug.

POST 12Original post

Frank: Are you nuts? Plugs on your car are good for 60K miles. If you are bored, I can think of plenty of things that you and your fiancee can do there in Atlanta.....

POST 13Original post

Both Bosch and Beru are used as OEM plugs. You need to get the recommended snap-on wrench and extention. There is just enough room for this combo to work. They are not the easest plugs I have ever changed. Mine had 30k on them. With a coil on each plug I doubt you will have any need to change them more often then 30K miles. Any notice in performance is your imagination unless you have some engine problem causing fouling.
