Inlet Manifold

 

Does any body know what the changes are I know the stems went from 4mm to 4.5mm dia.

 

Also '579 is this the latest manifold for 320d?

 

Any help would be appreciated

 

thanks

I am currently agonising over whether to remove my swirl flaps which happen to be the latest variety that is the part number ending in '577. I have had them in my 320d for 2 years now but have always been relunctant to fetch them out. This is because it is difficult to locate a specfic case of failure on the latest version - plenty of hearsay though. Also there are some negatives that is loss of torque at low revs and mpg taking a hit! Some say that it may effect the life of the turbo! Also selling on a car which has been "modified" may not be appreciated by the buyer(garage or even Franchise). Generally I opt for cleaning/inspecting the Inlet Manifold on a yearly basis. However both alternatives are costly although the over kill method has its merit. I can locate a garage which will do the job for £100 if I supply the blanks, although my local Indie will charge £150 incl blanks and clean the EGR as well. The panic merchants on other forums will always say deflap.  So which is best ; clean and inspect or deflap! Personally I prefer the cleaning op as I know my Inlet Manifold is in good condition but ...........
