Owens Racing™

HARRISSPEEDWORKS is my only choice for nitrous and nitrous related products! I called Matt the other day asked about a carb kit. He told me his main focus is the EFI kits and then done a little math. He told me honestly to look around at other carb kits from other vendors for better pricing. Now tell me this guy is not out there to help a fellow racer.

Great product, Great Support. One the best people I have dealt with in a while.

Thanks Matt

your happy customer,

I just bought my TR6's. (prepping for kit.. SO soon, it's scarry!.. )

Do you have a guestimation on mileage?? THey're not expensive plugs. MY TR55's I think are about shot at 16k miles. A couple hard runs on them.

Having to run the Autolite Shorty header plugs (3926)
on my AFR heads with SLP 1 3/4 headers because of
burning the boots.

Going Nitrous and trying to find colder plugs from the
3926 running now. Have looked all over for this info and
can't find the hotter or colder plugs in this type of plug

Any help or info in this case
Thanks

Which plug should I use with trick flow 21° heads on an lt1. About 400rwhp on top 150 to 200 shot.
the trick flow chart doesn't have the nitrous recommendation like the others so I'm slightly confused.
