Changing the spark plugs for tune up

There are a number of ways and if you ask five mechanics, you may get five answers that are the best way.

However, I have done it from underneath but if you don't have a car lift then this is pretty difficult.

The other way is to literally lay on the engine and do it by feel.

The last way that I have had success is to remove the wipers and cowl panel and then that will give more room.

I am attaching the info below from the manual. This gives a little more detail on how to do the rear bank.

Please let us know what you find with this and if you have other questions.

Thanks
