from the pros I've talked with, BG is the cat's behind. spoke with a transmission expert this AM..he has a BG transmission flusher that costs $4,000 and said it is quite the tranny flusher. while I realize that BG may not be the cheapest product on the market, neither is a mercedes benz engine. I work very hard to try and use the best products in the engine.......one of the major items I am attempting to correct is the air filtration. WIX makes a paper air filter of which I am not entirely happy with. I am planning on jury rigging a new cold air intake filter via a retrofitted 420SEL single outlet air cleaner. that should help keep more dirt, sand and junk out of the motor.

A recent conversation with a racing mechanic turned me onto the evils of dirt, sand and any other particles that pass through the air cleaner into the engine. sand and grit is the enemy of any engine and needs to be filtered via the air intakes any possible way you can stop it. you might lose a few horsepower in the process but beats the premature mechanical destruction of the engine via internal "sand blasting". in my opinion, a paper filter isn't good enough...dirt flies right on by.....
