The 'Trap Door Spider Nitrous Plenum System' incorporates some of the most advanced technology ever applied to a plenum design. This incredible design not only looks impressive but more importantly it will produce outstanding results on all V8 vehicle applications.

By being mounted underneath the manifold it's hidden and keeps the manifold free of excess pipework.

The unique shape of the Spiders discharge tubes (legs), combined with its unique flow path, ensures minimum phase change and maximum nitrous density arrives in the combustion chamber, resulting in the best performance gains from the least amount of nitrous.

The discharge tubes are manufactured from malleable brass, so they can be individually contoured to optimise the point of injection to suit different inlet manifold designs. The Spider is capable of flowing a massive 700 bhp with dual nitrous Pulsoids.

The Trap Door Nitrous system is only available in a dry nitrous configuration at the moment.
