# Skunk2 Pro Series 03-05 Nissan 350Z/Infiniti G35 5/8 in. Intake Plenum Spacer Skunk2's revised Nissan/Infiniti VQ35 Composite Intake Plenum Spacer V2.0 is dyno proven and road tested to outperform all other intake manifold plenum spacers. Skunk2's Intake Plenum Spacer V2.0 features a number of improvements, including a thicker design that increases plenum volume, lowers intake temperatures, and allows the engine's front cylinders to breathe more efficiently. All of this results in gains as high as 10 hp, increased throttle response, and a fuel efficiency increase of more than 2mpg. Unlike competitors' spacers, Skunk2's Intake Plenum Spacer V2.0 is constructed from an aerospace thermo-polymer composite that offers superior thermal insulation characteristics when compared to aluminum spacers or other heat-insulating gasket materials. A unique, industry-first, each plenum spacer's perimeter is injected sealed for tight fitment, eliminating the OEM gasket. Skunk2's plenum spacer is also easy to install and is packaged with all necessary hardware, including the necessary components to bypass the throttle body's water lines. - Not For Use w/Factory Strut Tower Bar - Lowers Intake Temperatures - Increases Plenum Volume - Gain Horsepower This Part Fits: Year Make Model Submodel 2003-2005 INFINITI FX35 Base 2003-2005 INFINITI G35 Base 2004-2005 INFINITI G35 X 2003-2004 INFINITI I35 Base 2003 INFINITI QX4 Base 2005 Nissan 350Z 35th Anniversary Edition 2003-2005 Nissan 350Z Base 2003-2005 Nissan 350Z Enthusiast 2005 Nissan 350Z Grand Touring 2003-2005 Nissan 350Z Performance 2003-2005 Nissan 350Z Touring 2003-2005 Nissan 350Z Track 2003-2005 Nissan Altima SE 2005 Nissan Altima SE-R 2005 Nissan Altima SL 2003 Nissan Maxima GLE 2003 Nissan Maxima GXE 2003-2005 Nissan Maxima SE 2004-2005 Nissan Maxima SL 2005 Nissan Murano S 2003-2005 Nissan Murano SE 2003-2005 Nissan Murano SL 2003-2004 Nissan Pathfinder LE 2003-2004 Nissan Pathfinder SE 2005 Nissan Quest Base 2004-2005 Nissan Quest S 2004-2005 Nissan Quest SE 2004-2005 Nissan Quest SL ## Details - **Price:** 314.78 CAD - **Vendor:** Skunk2 Racing - **Type:** Phenolic Spacers ## Variants | Variant | Price | Available | |---------|-------|-----------| | Default Title | 314.78 CAD | In stock | ## Images - Photo - Primary - Photo - Primary - Photo - Primary - Photo - Unmounted - Photo - Unmounted - Photo - Unmounted --- > Source: [Standard Auto Part](https://www.standardautopart.com/products/skunk2-pro-series-03-05-nissan-350z-infiniti-g35-5-8-in-intake-plenum-spacer) > Updated: 2026-07-01
