Having the TRD CAI really makes this job a breeze...
The #2 bank required removing the engine shroud cover,the 2 brackets for the intake and moving a couple of hoses around on the driver's side to allow you to get to everything.
I have the TRD Cold Air Injection so the #1 bank was a breeze.
Changing the plugs made the TRD/CAI a real bargain, every 30K is the plug change interval and not having to R&R the air filter canister saves alot of time.
As a foot note,I have had LC's for 20 years and this was the first time that I used the Toyota Spark plug wrench that comes with LC's and I was surprised at how easy and effective the Toyota spark plug wrench was with this truck.
