Use this aluminum plate if you plan on moving your EGR valve to an other place. Will require a gasket and/or RTV to seal against intake manifold.

User needs to provide two of their own M8x1.25 bolts. 10mm to 20mm in length.

Tired of rusted, ugly exhaust manifold hardware? Pick up this set of studs, 12 point nuts, and washers for your Protege!

Studs, Stainless, Polished, 12-Point, M8 x 1.25mm, M8-1.25mm, 1.75 in. Length, Set of 10

• P.E.P. manifolds are 304SS throughout! Never worry about rust or failed coatings.
• Utilizes 1/2″ flanges 4 mm thick walls to ensure strength with a low weight
• Positions the turbo in the stock location and is flanged for all T2 turbos (including but not limited to the stock turbo)

• An O2 bung in the collector for the stock primary O2 Sensor
• An EGR fitting which is positioned so that you can reuse your stock EGR tube, but the tube may need some slight adjustments in position for a perfect fit.
• 8 x black oxide socket cap bolts to replace the factory manifold bolts or optional upgraded stainless bolts or ARP stainless studs and nuts

• Use Anti-seize on all exhaust hardware
• Use optional studs wherever possible
• Cut the short end of an allen wrench down to about 0.75″ in total length so it can fit into some of the tighter spaces (such as the center bolts)
• Ball end allen wrenches will be very helpful throughout the install.
• The M20 threads on the EGR fitting can be very difficult to start especially if the alignment isn’t perfect. To make things easier loosen the EGR tube support bracket near the water neck and the nut at the intake manifold. With these loose, it becomes very simple to get the EGR fitting started at the exhaust manifold. Snug everything down once all threads are started.
