Fact is all things made for BMW (and esp M cars) are overpriced.
Well the plenum is a very expensive part which also depends on the material it's made from.... The carbon air box on mine is very pricey I guess. Also GPower has different spark plugs which are ridiculously expensive.
But as for being overpriced, I have to agree because I am the consumer
Although I have seen first hand what kind of work goes into the R&D side and you can understand why the price is so. Some companies can spend over £100k on R&D so think of how many kits they have to sell to get a return let alone a profit.
