Steve Scherer Posted January 17 Posted January 17 Wife’s 2010 RX350 with 71,200 miles. Engine runs fine. While replacing the coolant I examined the front most three spark plugs. All have consistent 1mm gap and look used, not abused or worn. Are these looking OK to keep in service at 14 years old with only 71k miles? Second question: When I unplugged the coil harnesses, a retaining clip came off. Can they be replaced in the harness, or did all three break off?
dcfish Posted January 18 Posted January 18 Why can't you just put the retaining clips back in place ? Plugs look OK, When in doubt replace them...

dcfish Posted January 22 Posted January 22 Maybe something like this...Or buy new connectors and push the pins out and re insert into new connector
