Dumb Question: How many spark plugs do I need?
 
I think I only need four for my 84' n/a, but I've never messed with spark plugs before so....

Thanks!

Tony,

Yes, you need four. Just remember #plugs=#of cylinders.

Eric

Yes, 4 spark plugs for a 944.

But I think there are some cars out there that require 2 spark plugs per cylinder. I think some 911s are like this.

Am I right?

Doug914 09-17-2001 10:52 AM

Yes, and some newer Mercedes models, and European V-6 Alfas...and rotaries, come to think of it, with a leading and trailing plug per trochiodal housing.

I knew I should have qualified my statement. Most of the time #plugs=#of cylinders.

*sigh* why can't they invent a twin-plug head for a 944 like they did for 911s and 928S' http://www.pelicanparts.com/ultimate/biggrin.gif

My Ford Ranger has two per cylinder, it doesn't run worth a crap tho! I run the Bosch +4's in my 951.

Goku 09-18-2001 09:11 AM

Aren't you not supposed to run plat. +4's on a turbo?

Dave951 09-18-2001 11:15 AM

Goku is right. The +4s have too much material(the four ground points), get hot, and can cause detonation. Most 951 owners use Bosch Platinums(single ground).

HTH,
Dave

Not suppose to be anything such as a dumb question, but this really is a dumb question and downgrades this site.

Euro, the 928 never came with dual spark plugs (per cylinder)... Come to think of it, that would've sucked from a maintenance point, 16 spark plugs?

I have herd several viewpoints on the +4's, I don't get detonation from them but I run around 97 octane also to keep detonation to a minimum under high boost.

Hey 3sonfather:

**** you

I agree with Tony. How are people supposed to learn if they don't ask?
