Discovery - The Ultimate EGR Guide

the EGR system redirects exhaust gases back into the engine along with fresh air through the inlet manifold. this was done to reduce exhaust emissions but can over time clog up the system & reduce performance

The first thing most disco owners do is fit a blanking plate between the egr pipe & the exhaust manifold.

you can get the blanking plate kits from here
