Hi, my name is Connor and I own a 2011 cruze eco MT. I just put a cold air intake on and I'm going to change the coil packs and plugs but I am unsure of what spark plugs to buy and about the plug gaping. Any help would be appreciated, thanks.
Welcome Aboard!
Tips to ensure no misfires occur:
Remove the coil pack. If the boots are stuck on, use a small screwdriver or pick with some dielectric grease on it to go around the outside of the boot and then possibly the inside of the boot to help aid in removal.
Remember to (p)re-gap your plugs to .028, (0.24 if tuned)
Set gap with the black portion of this tool.
To increase the gap size bend the ground strap up to the desired height. DO NOT LET THE GAPPING TOOL TOUCH THE
IRIDIUM CENTER ELECTRODE OR PORCELAIN.
Measure the gap with feeler gauges.
Throw this away.
Torque to 18 ft-lbs with no anti-seize on the threads of a stock type plug.
Ensure the boots have no rips/tears or holes in them, lightly coat them with dielectric/silicone grease and make sure the resister springs are clean and not caught up in the boots when you install them.
If the plugs look bad, consider these:
-BKR8EIX-2668 (iridium plugs), ~$25, expect ~10-15k regaps on these, ~40-50k overall life.
-BKR7E-4644 (nickel/copper plugs), ~$8, expect 15-25K out of these plugs, with a regap or two required at 5-8k intervals on stock tune.
