M300KOG

Thats it then... I am having a go myself! I did change the air filter myself recently so I am practically a BMW engineer

Thanks Dave! I have some quotes for a mobile chem clean which is suggested is an upgrade from the hydrogen clean. I wasnt sure if it really works or not, lots of people tell me no, you must get it manually cleaned or blasted. I wonder if I could have a go at removing the manifold and swirls myself and clean it at that point, I am pretty practical with tools but terrified of touching my car!

Hi! First post... go easy on me. My inlet manifold is caked with carbon and the swirl flaps are on thier way out. I was thinking of buying complete new inlet manifold as I get trade price on parts. My question is, is there brand of after market part I should look for or some to avoid? Prices vary from £175 to £500. Thanks
