I got a set of these and was really disappointed cause everyone spoke so highly of them. I gap them to .32 for factory setting and such. After putting them in, I notice a massive power loss and my car became hard to start. My car starts on the first time easily everytime on the OEM plugs and with the NGK i had to crank it 3-4 times to get it turn over. After about 3 days, I got sick of it and put my OEM plats back in.
