Sluggish...

[Blood on Blood]

Hello,

For the past month I have noticed my 03 Cobra (10,000 miles - stock except catback and K/N filter) has become a little sluggish and the gas mileage has decreased a little. Granted it has been hot out, but...

So, I was thinking about changing the spark plugs and fuel filter.

Has anyone had any luck with the Autolite or Champion spark plugs that are made for the 03 Cobra? Just checking prior to buying the $10 a piece stock spark plugs from the local dealership or $12 a piece Denso spark plugs?

Thanks

Dave

Air filter and fuel injector cleaner are good places to start.

The K/N filter is about a month old (approx. 1000 miles), but I will take a look at it...

Injector cleaning, sounds like a good idea...

Thanks everyone...
