sku: H-MAPCOL4

Map Sensor collector kit for 4 cylinder with individual throttle bodies.

This kit includes 4 x M6 stainless steel vacuum nipples to be fitted to each intake runner.
The silicone hose supplied has enough length to have four equal length vacuum hoses from each of the intake runners to the supplied collector with 1 meter spare for connection to the MAP Sensor. Special self clamping hose clamps provides a secure fitment of each of vacuum hoses on each of the stainless steel barb fittings on the runners and collector.
