Cheapest place for NGK 3334 plugs?!

[SL0BRA650]

I'm planning to do a tune up on my 04 cobra. Currently the car is tuned with NGK 3334 spark plugs and I would like to stay with them (to keep the tune in track). Unfortunately the cost for 3334 NGK plugs are ridiculous! Anyone know where I can find a good price for them?? If not, what's your opinions on the "br7/tr7 plugs" and "tr6 plugs?" Would it mess up my tune if I go with either one, even if I keep the same gapping spec?? Thanks!

I would talk with your tuner to see what he has to say

Rock Auto is where I buy plugs. Way cheaper than any other online vendor.

I run TR6s on my car.
They are about $2 each and easy to get.
Changing plugs wont mess up your tune.
How much boost are you running?

My 04 cobra was tune with TR6s by the previous owner. Car runs and idles fine.
