This week I had my Timing belt, water pump, tensioners and Serpentine belt replaced. I installed new cabin air filter, had my oil change done with Royal Purple 0w-20 and Mobil 1 extended filter and i changed my spark plugs to the new NGK Ruthenium spark plugs. Best upgrade I have done plus they are cheaper than those Lasers IR so that was a plus!
Getting better gas mileage and I dont have that unburnt fuel smell coming from my exhaust ( I have had that smell even when i got the car new). These Ruthenium spark plugs really do what they are said to do.
