That's not as silly a question as you two make it out to be. For a long time, the boxer engine used 12 plugs!

Fair enough. Some Carreras without direct ignition used 12. But come on - while it may have been a legitimate question - It was also too hard to pass up on the humor side....

AFAIK, no flat six engines in any Porsche available for sale had twin plugs. (that is, 2 per cylinder).
HOWEVER, Porsche Racing used twin plugged cars, and it's also a popular modification on Porsche engines for track/racing cars.
That being said, yes, the SIX CYLINDER Boxster uses SIX plugs.

No, they were in production for a LONG time with 2 plug heads. I'm not sure what year it started, but it went all the way to the 993.

964 and 993 motors had twin plug engines - 12 plugs.
Many folks modify Aircooled Porsche 6-cyl motors to be twin plug designs.
Your boxster only needs 6 plugs. If you are adventurous and want to save some money and learn a new skill, replace them yourself. If not, a dealer will be happy to help you out.

I believe that guy who said that the "BOXTER" once used 12 spark plugs was talking about the original inventor, from wich the BOXTER engine was named and designed after. NOT the Porsche BOXSTER! So he is probably right. :dance:

I've never heard of a "BOXTER" motor.. I have heard of a Boxster motor and a "BOXER" motor

my car needs plugs pronto! wish my old mechanic was still at my disposal. The guy won't touch a Porsche. Too bad he's the only 100% honest businessman I've ever dealt with when it came to cars.

1)Stay out of trouble and only use stock plugs. This will guarantee true compatability and will come pre-gapped.
2)Double check the gapping of the plugs. Although I have never had one off...by much...I can only imagine its possible.\
3)Jack up side of car, remove rear wheel, remove wheel liner and TADA!!! 3 plugs staring at you. You will need to contort a bit to get the tools in there but it is NOT difficult and you do not do this from the top of the motor access.
--This is a very easy DIY. Give it a try and once you do plug #1 you wil fly through the other 5!
Good luck!

Hi,
Twin Plug designs are not new or terribly radical. It sprung from early aircraft engines. Ferrari, Masserati, BMW, Aston Martin, and especially Alpha Romeo (in addition to Porsche) have been using Twin Plug designs for years.
Btw, the Boxer engine is not named after the inventor (Karl Benz, 1896). Properly known as a horizontally opposed engine, in which the corresponding pistons reach TDC simultaneously, thus balancing each other with respect to momentum. Original horizontally opposed engines were 4-cylinder and so the engine acquired the nickname Boxer because the reciprocating pistons resemble a Boxer throwing a combination punch. Fyi...
Happy Motoring!... Jim'99

Thanks for the trivia! Now can anyone answer my question about the differences in the "s" type plugs and the regular 2.7?? Please look at my earlier post. Also, is there a better spark plug wire I can get? Magnacore? MSD? Anyone? Might as well change those while I'm at it.

Hi,
The OEM Sparkplug specs are:
- 2.7L - Bosch FGR 6KQC
3.2L - Bosch FGR 7KQC
- Beru 14 FGR 6 KQU
- Beru 14 FGR 7 KQU
Torque spec is: 30 + 3 Nm (22+2 Ft. Lbs.)
Your car doesn't have spark plug wires in the traditional sense. It uses a Coil-on-Plug and so there's no advantage to using a different wire, such as you mention, nor am I aware of any aftermarket ones even being available. Hope this helps...
Happy Motoring!... Jim'99
