If not gapped right your car might start shaking, or even stall or worse no star.
Autolite 3076 gapped to .025
the plugs are already gapped On edit: That is not an answer, and you never install plugs without checking the gap. The correct answer is .035".
spark plugs for vehicles with electronic ignition come pre gapped when purchased .044
Maybe when they put the spark plugs in they were not gapped right or they maybe the wrong spark plugs.
Buy the correct plugs and they come pre gapped.
The correct spark plug gap for a 2000 Toyota Corolla is .043 inches. Most spark plugs are pre-gapped, but its best to check before installation.
Go to your local Honda shop and get the correct NGK plugs. They will come pre-gapped. This applies to all NGK plugs. You can verify this at their website. brad The manual says the correct gap is 0.8-0.9 mm (0.031-0.035 in) if you happen to get plugs that are not gapped. Hope this helps.
Yes, all spark plugs need to be gapped... but make sure you keep in mind that if the gap is not correct - if there is not enough gap, the spark will not be big enough, and if it is too wide, then there will be too much spark. Standard seems to be .45 but I would check with a dealership near you for a size recommended by them, the underhood specifications, or the brand's specs for that application, as they vary from 44-54!
The gap needs to be checked before instillation.
most spark plugs should be checked and gapped annually. if your spark plugs are used up you should replace them
I put NGK iradium pre gapped plugs and they work great.
The spark plugs should be gapped to .040 inch.
