Set of 8 UF230 Ignition Coil 4504 Spark Plugs V8 Compatible with Toyota Tundra Sequoia Land Cruiser 4Runner, Lexus GS430 GX470 LS430 LX470 SC430 2000 2001 2002 2003 2004 2005 2006 2007 2008 2009

Those coils and spark plugs were a straight fitting to the factory OEM, very easy installation. Tips: check crankcase sensor wire that it doesn't touch the serpentine belt, antiseize sparkplugs threads, torque to specs (12lbs-ft), dielectric grease on the tips of the coils, lock the threaded tips of the spark plugs so they do not unthreaded (just notch the thread with plyers). Original engine error "missfire cylinders" was totally cured, check engine light was cleared, engine idle returned to stable and normal. Injectors cleaning next, while installed.

It was very easy for me to install for a do it yourself. I thought it was a great value since I had shopped around trying to get good value for good parts felt the difference in power and take off

Everything plugged right in went good and took care of my sputtering problem

engine light came on recently code read misfire cylinder 1 .. i changed one of these oem with the original coils i saved ( old coil was still good ).. was fine until another month or so another code misfire cylinder 2 this time had to clean the platinum spark plug looked dirty and needed to be cleaned i used another original old coil.. my truck 2001 tundra i take care since 2001 original owner .. I'm going to buy iridium plugs .. for me it's worth checking them all now and will save the platinum plugs for emergency ..bottom line truck runs idles nice but after two years .. i want to try new plugs instead trying to clean two year old pointed platinum if the coils should fail I'll know but coils shouldn't go bad in a couple years..anyway next coils I need should it happen will be the old ones i saved

I installed these as I wanted tge red color, saved my 8 original... Over 18 months I was back to 7 original coils. So just went back.
