Replacing my spark plugs this weekend on my is350

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....

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.
