If u blow smoke into the intake manifold and you see it leaking due to a crack, it's cracked. Believe it or not, there is a unit that produces smoke without moisture that you can use to locate leaks. When he said "smoke" test, the tech wasn't suppose to smoke drugs and diagnose your car or have the tech undergo drug testing. I checked on Dinnan all i saw was throttle bodies. My questions are does that sound right? What should a IM cost for a reapir on a 2001 530i? If I am replacing it should i replace with a performance one to allow better breathing? Do thye make them. he said if that is the issue it will be about $700.
N54 intake manifold crack#
He is now suggesting a crack in the intake manifold. But every sensor it says is bad he goes to check it and its brand new ( I have spent about $700 replacing cam shaft sensors, previously mentioned MAF temp sensors etc.) and he said he traced all the engine wiring and everything looks good. He says the computer is still throwing codes for faulty sensors and bad MAF and a vaccuum leak. So I took it to another highly recommended shop and he has been trying to figure it out for a week now. Still continued to to have issues with loss of power as the engine heated up. And bought new OEM MAF, to replace aftermarket that I was told was bad. one shop said it was a vaccuum leak so they replaced a hose. I have been having a few issues with loss of power. Ergonomic appeal and lifetime structural guarantee.My car is at a local indy.Professionally Tig welded in house by our highly experienced fabricators.Precision CNC machined billet base, with hand made 3mm smooth design plenum dome.These manifolds can be supplied in 3 finishes, Raw, Polished, or powercoated Black, for the stealth look.Īs with all Plazmaman inlet manifolds, these are packed with many features such as: The fuel rail comes with all mounting hardware, including stainless steel fasteners and CNC spacers/brackets. The fuel rail accepts 14mm top feed injectors. For the additional injector option, we include one of our CNC machined fuel rails. OEM factory intake sensor will also bolt direct to our intake.Īn added feature of these manifolds is that they can be ordered and manufactured specifically to suit factory 6, or 12 injector operation (Additional rail added to top side for extra cost). Our BMW Intake manifold is designed as a standalone manifold, this manifold is bolted directly to the cylinder head, also using the Factory OEM DBW throttle body operation to maximize airflow.

The inlet manifold dome utilizes a hard temper 3mm sheet alloy surface that has been made to shape in house with advanced forming techniques. Multi axis HAAS CNC machines ensure that all the one piece billet bases have tolerances to within. Plazmaman inlet manifolds utilize some of the most advanced manufacturing techniques. The engineers here at Plazmaman Australia headquarters had only one thing in mind when they designed the BMW N54 Inlet manifold - to release a premium quality item that ticks all the boxes. *** as can be seen in pictures - the Plazmaman intake outperformed another leading N54 intake in back to back dyno runs. Plazmaman Premium quality BMW N54 Intake manifold - with optional extra 6 Injector rail for bigger HP requirements.
