First of all, THANKS for offering this product/service.

Next, I know that most want the one step colder plugs, but for those who do not, will you eventually offer this setup in the FACTORY stock heat range as well?

I can add that - to date I have not received one order for stock heat range. I usually have 10-20 sets of 6510's here at all times. I don't have any 6509's in stock, I was waiting for the first order to bring some in to be quite honest.

That's really awesome. The first time I got spark plugs on my srt 4 I had to learn how to gap them and I was always worried that I did a bad job, and probably did.

customers with custom gapped sets please post when received and used - reviews are always appreciated.

These plugs ship same day in most cases

Do you need a tune with the 1 step colder plugs?

*edit
I just added custom gapped 6509 's (stock heat range) for stock and up to approx. 50 hp additional over stock before you want to bump up to the 6510 1 step colder option

thanks!

M-Sport should enjoy this added option

any issue in running the colder plugs with just the bolt on/tune stuff?

probably not but I did run into a conversation on FB with Randy of Mountune.
In the SRT-4 community the cars go from running 7-9 psi at 285 bhp to well over 20 psi and over 100 bhp over stock. 1 step colder plugs is a no brainer in those applications.

For the Fiesta, if you are less than 50 bhp over stock you should be looking at the stock heat range with a gap of .025. Makes perfect sense.
Over 50 bhp from stock power levels go for the 1 step colder plugs

IF you do a lot of 'short tripping' (like less than 25 minutes of continuous driving) in the cold winter, they are probably not your best choice.

On the NGK site they claim that 6509s "don't fit" the FiST. Their recommendation is 94769 ILZTR6A8G Laser Iridium Plug... The gaps are also different - 043" (1.1mm) for the 6509 and 031" (0.8mm) for the 94769. I am wondering where this comes from...

we offer the 6509 if wanted but the 6510 can be used on all vehicles regardless of modifications added
suggested gap .027

This is an important post. Answer is YES, a tune is needed before a colder step, and even then, may be a negative move. Keep some OE heat range plugs around and do your own testing.....

if i am on Dizzy stage 2, with FMIC and cat back, i don't think the gain is close to 50 at all, so i shouldn't use 1 step colder plug?
