Thanks for the info. What was the outcome with the Radflos?i bought the same kit - had it shipped USPS as mentioned. i did have problems with my Radflos, and had to send them back for warranty work, which was a huge hassle. to top it off, apparently there isn't supposed to be warranty on Radflos sold by PRG outside of the USA, as it competes with other dealers. however, only PRG has these specific Radflos for the Frontier.
i would possibly consider other coils that may be warrantied or serviced here in Canada. Greg and Jen are both great to deal with, though sometimes really slow to get back to you.
