07 M35X Fuel Injector Size

[LLSmoovE]

What's going on guys. I've had my 07 M35X for a year now. I'm beginning my performance upgrades on my baby. Just put in an Injen Cold Air Intake. I got some Kinetix SSV High Flow Cats ready to be put on and then I'll decide what muffler to put on afterwards. But for the next few months I'm gonna focus all on performance in the engine. I'm getting a plenum spacer and thinking of a throttle body spacer if those really work as well as maybe a 75mm throttle body. But with those I dont kno what tuning was done to the car before i got it so I'm going to be giving it a full tune up as I just hit 113,000 miles. Spark plugs, coils and I'm thinking fuel injectors. Does anyone know what size fuel injectors are used from the factory? I wanna kno because I do want to increase the cc size but I dont qant to go drastically over what the factory has initially used. In addition does anyone else have any ideas of what else I should take care of in the tune up and your thoughts on changing all my vacuum hoses to performance hoses? I'm all ears

The plenum spacer and an UP-rev tune will make a noticeable difference, I'm sure. However, CAIs have virtually no effect and can even decrease HP in some cases - the only real benefit is that they look sooooo amazing (but nobody else will see them). I don't know about changing the injector size. For the most part, the engine was developed and designed to use what's already on it. I don't want to poo on your parade, but considering it's a V6, there is definitely a limit to how far you can tweek it before you over-stress / damage it. Hopefully, other members may have experimented in these areas and can lend some advise.
