Allards EGR removal pipe - done.
take it back off as in the pic above, but then take off the intake manifold (8 nuts) take 10mins tops of touchy feely removal (be careful not to drop a nut down the back, takes ages to find)....
soak the inside of the intake in carb cleanear for ages, an hour maybe, and when you tip it out you'll be amazed at the sh*te that comes out!
looks like an oil change
then wash in fairy liquid with hot water using a small brush to get in to the all the corners get it nice and clean
doing this will increase the size of the intake ,which i'd of thought you'd probably notice performance wise the power / airflow you've got!
i think mine was about an increase on average of about 4mm diameter where it bolts to the head, which doesn't sound alot but when the actual manifold is about ~20mm diameter, thats approx a min of 20% increase
when the intakes off, remember to wipe out the inlet holes in the head best you can
its amazing how much soot and oil vapour can build up.....
remember seeing a pic of an intake on this forum and it was virtually solid with this gunk
worth a few hours work IMO
