I never did pulse and glide, but anyway, the savings would come more from the longer lasting of the plugs than anything else.

It was my impression that modern hydraulic valve lifters were self adjusting. Is this not the case? None of the cars I drive indicate a valve adjustment interval except for my motorcycle. |

This is a Civic, right? Changing the spark plugs is the easiest thing on these. Pop the hood, there they are in a row, right on top in front of you.

I had my then-girlfriend change the spark plugs on my Civic. If you change the wires, they always say to change one at a time, so you can keep the order correct, but I forgot that step, and we seemed to figure it out well enough.
It was amazingly easy.

A 4 cylinder is easy. It wasn't quite as easy on my 1973 Jaguar XJ12 12 cylinder.  |

• The physical layout/arrangement:
A↑ (right bank: 1A..2A..3A..4A..5A..6A)
← FRONT of ENGINE
B↓ (_left bank: 1B..2B..3B..4B..5B..6B)
• The firing order: 1A..6B..5A..2B..3A..4B..6A..1B..2A..5B..4A..3B
It's really funny what seemingly useless numerical sequences a motorhead will remember, like my 340/6BBL (LA) engine: 1-8-4-3-6-5-7-2.

On my civic, platinums were -5.78mpg. Iridiums were -2.83mpg. Best were the stock v-power. Pump neutral, but butt happier with indexing.
This is on a lean burn engine that is very sensitive to spark changes. Haven't tried swapping out since I added the msd though. Can, they're near new collecting dust on the shelf.

acceleration
Is acceleration faster with platinum & iridium plugs?
