Code: 307-07-0400
Price: $226.10

Skunk2 Racing is proud to introduce its’ new VQ35 Nissan/Infiniti intake manifold plenum spacer (patent pending). This spacer is dyno proven to outperform aftermarket manifold plenums currently being sold. The skunk2 spacer effectively increases plenum volume, lowers intake air temperatures, and allows front cylinders to breath more efficiently resulting in gains of up to 10+ hp to the wheels, and increased throttle response. Unlike other spacers on the market, Skunk2 spacers are made from a special carbon composite material (carbon impregnated nylon-6) that offers superior thermal insulation characteristics which also increases power by keeping the upper plenum and charge air temperatures lower. Because the stock upper plenum is used, the engine retains a factory appearance. 5/8” uniform thickness - not angled. Easy installation. Hardware included.* Factory plastic plenum cover and strut tower bar cannot be used in some applications.

I will sell it for 150 Shipped UPDATE: $125

does the engine sound a lil bit different after you install it? just wondering... and you can leave the factory cover on correct? im very interested.. thanks

 

I have it, and it does make the engine sound meaner. I was very impressed with it.
By the way, i got it for 175$

 

if you take off the two foam spacers on the cover, you can use your engine cover, but it will rub a little. not that much... since its not metal it wont conduct heat so the top of your plenum wont get that hot anyway...
I have it and love the top end pull.

 

I want it. I'll PM you

 

Sold
