So I got all my goodies for my tuneup on my 95 Astro

Bosch wires
Cap and rotor with brass terminals
Delco Platinum plugs
PCV valve
plug grease/thread grease

Question, I cant remember what the plug gap is for my 95 :doh:

Little help Astro brothern/sisters :bow:

.045 IIRC, amigo. If not someone'll correct me quickly.

*edit* Verified off my '95, above gap is correct at least for a VIN W

Personally, I gap them just slightly under spec (usually right out of the box like that) because it will slightly widen after so many miles and it's easier on your ignition components because wide gaps over spec need higher voltage to spark. Makes me feel better because sometimes I just forget about the things and run them a bit too long :oops: . Nothing like my friend though who ran his original plugs to 120,000+ miles and the gaps were insane with almost no electrode left :doh:
