i keep getting a cel for misfire in all 4 cylinders. there a local store that sells our oem plugs besides the dealer. They want so much for them.

 

Every auto parts store can get NGK iridiums, you will probably have to order them.. Napa is usually pretty good on prices. BAP imports might stock them.

 

I got mine from Napa. Plugs might not be your problem, but its a good place to start. My multiple misfire code ended up being bad injectors.

 

I bought Bosch plugs for mine and have had no issues.

 

Are the Bosch/NGK better than stock? or all they all pretty much the same?

 

OEM NGK Laser Platinum plug PFR7G11S, stocking part number 7772.

They have 4 in stock a the 27th Ave and Thomas NAPA store, you can order them at any NAPA and they will have them in two to three hours. Retail price is $13.59 each.

 

The NAPA store at University and Mclintock has 4 also.

 

I don't notice a performance different. My car still starts up the same and seems to perform the same. I haven't taken out the Bosch plugs to inspect them yet but I may just do that on tech day Feb.21.

 

There have been plenty of reports of Bosch plug electrodes breaking off and pooching engines - I would stick with either the OEM NGK Platinum or the NGK Iridiums.
