Well the intake on my 99' GT just cracked like i have read som many of these intakes do... Who the hell puts a plastic intake manifold on a "performance" car. The sad thing is all the others that i have read of on forums that have the same problem... I hate to say it but I might be looking at another manifacturer for my next car... Ford better get off their asses and complete the recall on these to include "non-service" vehicles... For those of you who dont know what I am talking about, try doing a yahoo search for 4.6L intake manifold and get ready to spend $600.00 plus to replace yours... 



Yea, that's right. It seems the clogged filter cause a super lean condition which led to backfires under acceleration trying to get up to speed, which caused an overheated EGR tube to melt a spot thru the plastic. I can give you a laundry list of crap that went wrong with the car. You want a GM over something like this? Go for it.
