Stainless Steel four branch manifold for Z22SE 2.2 16v engines from Piper. Improves flow through the mid and top end rev range with improved power and torque about 4,500 rpm, and on a standard VX220 5 - 6 bhp gains have been seen. This is a direct replacement manifold for the 'OE' item, so will neatly fit to any existing downpipe/cat assembly, standard or performance.
Will suit Astra G, Vectra B, VX220
RRP £349 I will take £280 for it. Ring Jon @ Courtenay on 01692404313
