Oh.. well if you look under your first post, there is an add for lots of injectors. LOL.. And I meant upgrade as in more CC's, not brand name. Don't get bigger injectors if your motor is still stock. And if your motor isn't stock (boost) and you're asking about injector cc's I think you may need to read up some more or you'll do some damage if you're not careful. As for brand "upgrading", Sorry man. Can't help you. I'd just go OEM so... Good luck!
