[QUOTE="leforte, post: 405311, member: 1943"] [SIZE="4"] M50 manifold mod only fits m52 single vanos engines. [/SIZE] m52TU or m54 engines uses a different manifold system and also a different cylinder head and inlet port design. m50 manifold can be "made" to fit but cost and performance gain/lost would be a real question mark on the reason to do so. to get a 523 to 525 performance, a tuning remap is all that is required.
