You won't need to change the gap. When you buy spark plugs for most modern cars the plugs are usually preset to the correct gap. It is usually only adjusted if you are changing the performance level of the car.

Since it's electronic ignition, plug gap should be around .040 with a feeler gage. @ .032 for earlier.

In your owners manual

Plugs come pre gapped

Gaps are on the parts & plug mfg sites

Spark plug manufacture sites & the internet

Any plug you buy has the gap on the web site

Hello and welcome to FixYa!

As a first course of action, I strongly suggest that you have an engine tune up. You may need to replace the spark plugs for if it has a big gap, corroded, full of carbon or faulty it will have poor fuel burning, which can consume much.

New spark plugs can result to better fuel burning.

Hope this helps and thank you for using FixYa! Have a good one!

The spark plugs should be matched up with the old ones to be sure that are the same as the new spark plugs and that the threads are not too long or too short and if the spark plugs were pre-gapped or if they need to be gapped, and the auto part store should have given you that information along with any spark plug gap because some spark plugs you can not set the gap on or they will be damaged. The spark plug gap should also be printed on the emission label out under the hood. Also, the other three spark plugs and wires should be changed to complete the ignition tune-up.

The spark plug gap should be the same amount between all of the spark plugs, and the farther apart that the gap is between the spark plugs the rougher the engine will run and idle, and the closer that you get to the same spark plug gap between the spark plugs the smoother the engine will run and idle.

It is also very important that the spark plugs be connected to the correct terminals on the coil pack or the engine will have a severe mis-fire and it will set a mis-fire DTC (Data Trouble Code) and cause the check engine light to come on.

Here is a firing order diagram to help assist you and let me know if need help with this diagram or if you require any further assistance.

these plugs should be NGK BKR5ES-11 or PK16PR11 ND and plug gap at .044". hope this helps. cheers.

Under the hood you will find a white sticker, about 2-3 inches wide. On it will have the engine size/group and the spark plug gap and other service information. Good luck
