Hey guys, so this weekend im doing a tune up on my 86 944 NA and I was wondering what spark plugs to install. The only mod i have done is a cold air intake. What spark plugs do you suggest????

My 87 is running fine on WR7DC's... I ordered two maintenance kits from vertex for a late car and that is what I received. Though I did get 12 plugs for 2 kits... where did my other two cylinders go... I want them BACK!

For "model/type 944", FSM says Bosch WR8DS or Champion RN-10GY, gap=0.7mm +0.1mm.

Not for my 'S' though (that's WR7DC).
