Thread: Hi, New here, hoping to learn a few things ?

Hello, I have a 2007 Pontiac Grand Prix, a very nicely fitted car, closer to a Cadillac in many things. I've done absolutely everthing maintenance wise, every fluid and belt, new coolant and filters. But I'm very frustated by the seeming lack of aftermarket system like a CAI which K&N says their looking to finish real soon, it's been five years now, how soon is real soon ? And I need to replace the whole set of fuel injectors over the summer.
