I also fabricated the EGR blocking plate myself because the previous one was too crude and lazy-looking.
BHPian x-o-b recently shared this with other enthusiasts:
Update: My remapped ECU will be delivered today. I can’t wait to plug it back in.
Meanwhile, I decided to move the EGR blanking plate from the exhaust manifold towards the intake side. The rationales were:
1. The plate would get way too hotter placed at the exhaust side and hence melt probably? At the intake side, the plate would stay cool because any exhaust hot gas would be colder comparatively, and there’s EGR cooler too.
2. Blocking right at the intake implies that all the cold air from the intercooler finds its way only and directly into the intake manifold, instead of travelling towards the EGR side and perhaps losing some boost pressure there.
In this process, I also cleaned the air intake hose. See how dirty it was:
And this is after cleaning it up:

I also fabricated the EGR blocking plate myself because the previous one was too crude and lazy-looking. This time I put some effort. The following pictures will tell the story:

Checking if the size is adequate ↑↑
Flattening Out ↑↑
Using the aluminum gasket as template ↑↑
Cutting to Size ↑↑
Grounded to remove rust and make it look presentable ↑↑
Looks like it fits ↑↑
Oh, by the way, I took extra care to sand down the edges so that it isn’t sharp and hurts me during maintenance, installation, etc. or damages automotive wiring.
Lastly, before I install the plate in, I have to ask a question to the experts here.
Should I drill a small hole in the middle of the plate?
Why? Because I have seen that done in many after market blanking plates. They claim that it keeps the engine light from turning on (the emission malfunction light). Are there other benefits to letting in a little bit of exhaust gas in? Personally, I like it completely sealed such that the engine gets to breathe only pure cold air at all times. Please do drop some views, thanks.
