Kinetix Racing V+ Intake Plenum | Fits 2003-2006 Nissan 350Z & 2003-2006 Infiniti G35 | VQ35DE Non-RevUp & RevUp | Cast Aluminum Upper Plenum | Unleash 350Z/G35 Power!

Unleash real NA power from your 2003-2006 Nissan 350Z or 2003-2006 Infiniti G35 with the Kinetix Racing V+ Intake Plenum that replaces the restrictive factory two-piece upper plenum on the VQ35DE Non-RevUp and RevUp engines, because the stock plenum has a small internal volume, sharp 90-degree turns, and uneven runner distribution that chokes airflow above 5k RPM and starves the front two cylinders, while the V+ uses a larger single-piece cast aluminum design with increased plenum volume, smooth radiused bellmouths, and a velocity stack-style center inlet that dramatically improves air distribution and velocity to all 6 cylinders, delivering proven +12-18 WHP and +10-15 WTQ gains with supporting bolt-ons and a tune by fixing the VQ35DE’s biggest intake restriction, and it’s a direct bolt-on for all 350Z Base, Enthusiast, Performance, Touring, Track and G35 Coupe/Sedan models including manual and automatic with no cutting or modifications required, and it reuses your factory throttle body, sensors, and lower plenum using OEM gaskets and hardware, and the aluminum construction dissipates heat better than the stock plastic to reduce heat soak and IATs during spirited driving, and the internal design eliminates the restrictive center divider and casting flash of the OEM plenum to create smooth laminar flow that improves throttle response, cures the front-cylinder lean condition common on tuned DEs, and gives you safer, more consistent AFRs across the bank, and every V+ is pressure-tested and flow-bench verified for even cylinder balance, and the low-profile design clears stock and aftermarket strut bars while adding a deep, aggressive intake growl at WOT that makes the VQ sound as good as it runs, and it retains all factory PCV, brake booster, and EVAP ports so you stay emissions-friendly with no CEL on a stock ECU, though a tune is recommended to capitalize on the airflow, making the Kinetix V+ the go-to bolt-on for 350Z and G35 owners who want to wake up the VQ35DE up top without going forced induction or dealing with spacer fitment issues.
