BASIC 5/16 INCH PLENUM SPACER FX35 350Z G35 M35

I have read many reviews of this product online prior to my purchase and can attest to what this spacer claims to do. Install: The install took me several hours because I like to take my time and am nit-picky when it comes to following directions. You also need some sort of mechanical ability to pursue this task, so if you can change your oil, you can definitely install this spacer yourself. There are many guides online that help simplify the install. Performance: My butt-dyno can definitely tell a difference with this spacer. I get more of a mid-range kick when adding a good amount of throttle. Overall, this product is great for those with a naturally aspirated engine and who are looking for a small extra kick in performance. The product had demonstrated itself that it is worth the money. I'm very satisfied with this spacer, plus the quality that is apparent with Motordyne products.

Took me 2 hours to install while taking my time and taking multiple beer breaks, very easy. More/better intake sound and also SLIGHTLY more/better exhaust sound. Took my '04 coupe about 50 miles after ECU reset to notice any power gains. Nothing drastic but noticeably better top end power, goes from 60 to 100 slightly faster now. Motordyne claims 10 HP, which for any bolt on is a no brainer. A MUST get if you own a G35.

All parts were included, delivery came in earlier than expected always a plus!! Only thing is car runs sluggish when I installed it possibly needs a tune but overall wonderful product!

The spacer is okay for the price, but the hardware that comes with it is super cheap and breaks before you can even torque it down. The bolts for the strut tower were also twice the size they needed to be. In the second picture, the one on the left is the correct size bolt( bought after receiving package) and the one on the right is the one that came with the kit. The bolts used to tighten the middle of the spacer snapped before I was even able to start torquing it down(first picture)

Works like a charm, I feel the power and the it was a easy install just follow there YouTube video online and ou should be alright, comes with everything you need except tools. Be careful with throttle body and I didn't used any lock tight. Didn't seem needed. You'll get your money back, if you decide to get rid of the car. just remove the spaced and sell it. Fits all vq engines in my case. Make sure to leave or hold the oem gasket on the plenum for when you want to get take off your spacer

this was the second spacer i have bought (the other Skunk2 5/8) and the power difference from stock is not too noticable but good for a bolt on. Compared to the skunk2 spacer the motordyne is much easier to install and provided all the parts and instructions. Great quality stuff so far. P.S. make sure to not drop the inner spacers down the manifold not so fun 30 minute detour.

Had everything I needed even locktite :) the power from this is amazing makes the car so much faster. The mods I have done so far are true dual exhaust and test pipes befor the plenum it would crackle and pop everywhere but now it seems to be more motor noise sounds good very noticeable power increase instructions are not 100% clear but YouTube helps no leaks or engine codes 2003 m/t 350z higher idol even after reset and first mod to lower mpg went from 21 down to 18-19 I redline my car daily and drift it everywhere so if you keep your foot out you may have better mpg

Makes the car feel new again, surprising little kick in power and a perfect addition to the sound quality of your exhaust Ps be carful while messing around in your open intake, my friend accidentally dropped a washer into my intake and we had to fish it out through the spark plug hole
