Change plugs with pulley swap?

mojosvt · 02-28-2006, 09:55 AM

My cobra has 21000 miles on the clock. Later this month I am installing a 2.76 BF pulley with a set of billetflow idlers. I am having her dyno tuned professionally with a Xcal2. Do i need to change my plugs? If so, what brand and where would I get them?

Sorry, I meant to post this in the 03-04 cobra section, please move me when somebody gets a chance

Yes, you should. NGK TR6's gapped at .035.

yeah after my first pull the tq was like 441 so MM changed the plugs and it made a big difference. Matter of fact Dan pretty much insisted that the plugs be changed my car has 13.300 on the clock

Yes change the plugs, exactly what NC03BlkSnake said.

Last year when I installed a 2.76 BF pulley with the BF idlers and a custom tune with the Xcal2 my tuner recommended a one step colder plug. I went w/the Denzo it22's. They are more expensive then the NGK but I have never had any problem with them.
