How To Upgrade The Intake Manifold Honda CR-Z

This is quite a common mod, taking a GE6 Honda Fit Manifold and making the holes wider to make it similar to the GE8 Honda Fit Manifold or putting in the GE8 Manifold. In this video I show all of the necessary steps.
This mod is well worth doing if you are looking for a couple more HP for relatively low cost.

Dude thank you for this video.. you helped me access my fuel rail to replace the injectors. It's super difficult finding videos/info on CR-Z maintenance

[@1Jackpulley]

haha no problem, i’m replacing the clutch and coilovers this weekend, i may make a video on that

Solid install brotha! Goodluck to your channel I just started mine too around my 9th gen civic si. I've always wondered what the engines looked like in this CR-Z's lowkey everything honda makes is dope!!

[@1Jackpulley]

Yeaaa, I got my CR-Z a couple years back and im just now starting to do mods and touge with it, quite enjoying making videos as well, planning on using a 360 camera next to get some third person view footage and hopefully a cool lil touge vlog. Ill give your channel a sub!

@JackPKZbin hell yeah I'll keep an eye out she sounds mean

awesome vid! also did this mod when i first got mine plus the k&n typhoon intake and might i say the mid range rpm definitely has some more power to em

[@1Jackpulley]

Yea, definitely not a crazy difference but just makes it feel more peppy in a way - next thing I wanna get is a throttle controller, as apparently they can make the throttle response more fun.

@@1Jackpulley i'm planning to get a tuner for that. Also because of the new exhaust i installed

[@jackwang860]

hey bro wondering if changing the manifold changed anything performance wise?

[@1Jackpulley]

yes, nothing drastic, but it got more lively and responsive, probably a few hp

[@jackwang860]

@@1Jackpulley is RB1 the intake that bolts right on?

[@1Jackpulley]

RB1 & RB0 both bolt right on, but with the RB1 the 4 holes need to be sanded/ported to make them thicker, then it is the same as the RB0, both go on easily as shown in the video@@jackwang860

Not an expert but I’m pretty sure this just increases the amount of air the engine can hold, but the air intake is still stock sending the same amount of air resulting in a slight difference but not much. Still worth doing on its own, but pair this with an after market air intake and the increase in power is so good you’ll have “a whole new car”, or so I’ve read on the forum. And vise versa, new air intake on its own is good but new air intake and new intake manifold is great. Pretty sure tuning the ecu to increase the rev limiter and air intake can make these results even better, but I’m also pretty sure that would mean you would have to increase fuel input to match the air and pretty sure that means you need new fuel injectors.

You could also probably pair this with the stock air box mod if you’re on a budget
