Stick with the stock plugs unless you're FI'd, nitrous'd, or running really high compression.

Assuming you've got a LS, use NGK ZFR6F-11. The plugs you have in there now are probably ZFR5F-11, which are heat range: 5 and the hotter of the two recommended plugs.

The recommended spark plug gap for B18A/B motors is 1.1mm, which is what they come pre-gapped at. The 11 at the back of the NGK part number is the preset gap.

Use a spark plug ring tool (looks like a big coin with markings all over the edges - typically found at the counter in a box or on a rack at Autozone stores) to check the gap and install.

While you're at Autozone, pick up some anti-seize compound. Use a 5/8" spark plug socket, which has a rubber holder for the back of the spark plug, and use it on a 6" extension.

Place the spark plug on the socket/extension and then apply anti-seize compound onto the threads of the spark plug. Don't go to sparingly or start getting all messy on it either.

Thread the spark plug in, turn to hand tight, and repeat with the other three spark plugs.

Then use a torque wrench to torque to 13lb*ft.

The spark plug socket might be a little difficult to remove after torquing them down. Just wiggle it a little and try getting it out at an angle.

Whatever you do, don't drop the spark plug or squash the electrode, otherwise you'll change the gap and have to regap it.

 

NGK dont go for anything but NGK

 

Teken saves my heiny once again.
