What sparkplugs does everyone reccommend?
 

Time for some new sparkplugs it looks like

WHat branks do you guys reccommend?

I was going to use NGK Platinum tipped ones, but I'm open for suggestions since I've only owned a Boxster for three months and I would like to hear some opinions

Keep it stock IMO...
 

Search the boards and you will find possible troubles with other brands for reasons unknown. Boxsters seem very touchy and temperamental with non-stock parts. I wouldn't take the chance. I changed mine a month ago and used the Beru plugs from the dealership. The new plugs made a noticable difference in throttle response!

Good luck!

Paul

really? Are the Beru plugs platinum tipped as well?

Basically I'm fine with getting stockies, but I would be interested with some other ones which may give better performance.

I know some friends who use those NGK ones on their Ferarri's

thanks for the info

I used the Bosch Platinum +4. Since that is what the dealer used the first time they were changed, I figured those were stock. They have been great and one of the forums Tool Pants listed confirms the dealer uses both Beru and Bosch.

Be careful messing around with it, though. Porsches are picky. The 928 was made to use a specific copper plug and does not run as well on the platinums and can be damaged by them, no matter how expensive. Personally, I'd stick with stock.

EDIT: Make sure you're using the right heat range plug and not just the +4 you can pick up at Auto Zone.

alright i'll do that then

thanks for the info

Is there gapping with the 4 pole spark plug??? Never saw one of these before!!!!!

:cheers:

no you dont have to gap those

Hi,

There is no performance increase to be had from using any brand or model of spark plug. To the Engine, a Spark is a Spark, More or Hotter is not better. Anything saying something different is all Hype. Go with OEM - none better...

I allways buy over the counter at the dealership exactly what Porsche said to use :)

Bosch!!! IMHO I try not to think I know more than the Boxster engineers :)

You outta read my Zimmerman rotor thread :mad:

Thanks PorscheGuy... I didn't think so with the post not over the pin, but didn't want to take any chances.

Hi,

I disagree. It's been my experience over the years with Pre-Gapped Plugs that a considerable number are improperly gapped, significant enough to warrant that they should all be checked.

Poor Quality Control at the Factory, to rough handling in Transit, may be the cause. Nonetheless, unless you're willing to remove them if the Car runs rough and the plugs require re-gapping, it's best to check them prior to installation. They may be Fine, but then again...

Ok ....

So how do I gap these???

There not like the typical plug I have used before..

:confused:

Hi,

Well at least check them B4 installing them. The more exact each is gapped to the others, the smoother your idle will be. I use a set of Blade Type Feeler Gauges. The best thing to do is use the comparative method. That is, use the Feeler Gauge which is one Up and one Down from the desired setting which is 1.6mm-1.65mm (0.063"-0.064"). The gauge one Up should not go in and the one Down should feel really loose. If you need to open the Gap, carefully use a needle-nosed pliers to open them. To close the gap, a lite tap with a small Ballpeen hammer will do the trick. The Tightening Torque is 22-24 Ft. Lbs. Hope this helps...

Nice Tx MNboxster Will be doing this tonight and will check the gap.. Picking up plugs from dealer after work.

Plugs are in!! That was the easiest plug job ever. The book really didn't say how to get to the plugs just the procedure. I am getting new rear tires removed them and got to the plugs that way. Made the job really easy... Not sure if somewhere here that was already written but FYI anyway. Much easier than from under the car IMO. As for the gapping I tried my best they were all pretty good from BERU only one or two that I had to adjust. Thanks again to all. Fuel Filter next then to the shop in April or May for the Top install and I wull be ready for the Summer(if it ever comes) Getting Snow again to day 70 degrees Yesterday 31 Degress today Gotta Love Ohio Weather....

Hi,
