ALL SALES FINAL
The Blox Racing GEN2 HyperTemp spacer keeps the original’s design and shape, but is now made out of a newer, higher temp polymer. The new material is intended to withstand the rigors of big boost turbo and supercharged engines that generate extreme intake, as well, as overall high engine temperatures.
BLOX Racing’s plenum spacer is the industry’s best selling plenum spacer for the Nissan VQ35DE. Easy installation and 100% bolt-on performance. Includes all necessary hardware for a quick and easy install.

Before ordering
Match the full SKU, dimensions, thread or bore size, finish, vehicle application and pack quantity to the intended installation. Where an application is vehicle-specific, confirm model year, engine, transmission, body style and any stated exclusions. Universal does not mean suitable for every installation; available space, interfaces and supporting components still require checking.
Installation and use
Follow current manufacturer and vehicle service information. Performance, braking, suspension, fuel, steering and safety-related components should be installed and checked by a suitably experienced person. Confirm required companion parts, settings, clearances and local road-use requirements before installation.

UK VAT-inclusive retail, current stock, media rights, structured vehicle fitment and market-specific approval remain separate verification gates unless explicitly stated above.
