Spark Plug Suggestions

Stick to what your dealership is selling,which should be OEM spec to your Boxster. It's not worth the 'added benefits'(if there really are any) with aftermarket plugs.

I replaced mine at about 60,xxx miles and the engine smoothed out a bit. I'll add that I don't believe my engine had the proper plugs before I made the change: the old ones were a 2 electrode Bosch. I replaced them with Beru Ultra-X, UXF79 0 002 335 601. These were purchased from Zim's Autotechnik, a company who often advertises in the back of Panorama. Hope that helps out a bit.

Dealer plugs are Beru. I heard Bosch may not be compatible due to heat range issues etc (do a search) even though those plugs are selling online. I have been happy with Beru...it's your safest bet with dealer plugs.

Hi,

That totally depends upon the Model Year. The 2.5L Boxsters used both Bosch and Beru plugs interchangeably.

And, you cannot trust the Dealer to have the correct ones. There have been several posts here where a Dealer sold Bosch +4 plugs for a non-egas Boxster - this is an incorrect plug. The non-egas cars use a Twin Ground as opposed to a 4 Ground plug.

Do a search for the proper plug for your car - this has been covered here ad nauseum. Hope this helps...

Happy Motoring!... Jim
