Description 20v 4age – Intake adapter to suit Nissan GTIR plenum chamber Adapts a plenum / air box lid sourced from a Nissan GTIR (SR20) pulsar onto 4age 20V throttles. Suggested for those needing a closed intake or any that will be running boost. Guaranteed to handle high boost levels without issue. Fits into the engine bays of right hand drive AE86 and others. Also works with other engines that have a quad throttle conversion such as the 16V 4age. Auction for adapter plate only, no second hand plenums are available for sale. No gasket is supplied, gasket maker / general sealant is suggested. PART UPDATE: The manufacturing process of these parts has been updated in regard to how the inlet transitions are machined. With the new process multiple cuts are machined away to form the inlet radii. Due to now using a larger radius it is expected that this change will increase the airflow into the inlet openings when compared to the previous model. This change can be seen in the last product photo.
