the best spark plug that i have found is the NGK Iridium spark plugs, I had the bosch platinums and i had alot of hesitation and hard time starting in cold weather or when the vehicle hadnt been used in hrs. I verified the gap on the bosch's and still no change, after about 20000 miles i removed them and found that they had been arced beneath the ceramic. I installed these new Iridium spark plugs and I have no hesitation on start-up and also I have a smooth Idle.
