If you want to buy from groupbuycenter.com, go ahead. If you want to establish a customer relationship with a premier tuning shop, buy from me. If you have problems with that kit, good luck getting groupbuycenter.com to even answer the phone.
Actually you buy the kit from
this site Also FYI, that's the import kit and you'll need to buy different fittings for your DOMESTIC car, the fuel connections IIRC are different and the import NX kit only has 3 jets--35,50,75--you'll need to buy anything over that. This kit comes with jets for 100 and 150.
Actually, FYI what your selling is the imprt kit also, they are actually the exact same kit and they are billed buy NX as being universal. If someone put a 150 or 100 shot on thier Zetec(this is that exact same kit so popular with the Focus crowd) they would be asking to melt a pist down.
Please don't take this the wrong way, I know that there is no substitute for good customer service, but for someone such as my self(broke in the army) every penny counts.
