Default Replacing my spark plugs this weekend on my is350

i printed out the diy thread. I have checked the gaps on all spark plugs. Bought everything from sewell. Any tips i need to know about? It seems to be not that hard to do and it will save me over $200 as well.

It's an easy install for sure. The driver's side plugs will be a little trickier, but still not that bad. Be sure you use a torque wrench when you install the plugs. Otherwise, you are good....

Will be doing this soon as well. I've read that to properly torque the plugs, the engine has to be cold. Is this true or not?

it was my first experience when i changed my spark plugs. unscrewing some of the spark plugs took alot more elbow grease than expected . after you do a test drive, double check the metal fuel line thats in the upper top right aarea and make sure is secure and not leaking fuel.

good luck on the nut in the upper back manifold that is hard to reach. You may want to find someone with small hands to reach in there for it.

No it doesn't have to be cooled down. I did mine after I drove hone from work. It simpler than it looks.
