k&n induction kit

[stew299]

hi guys,i've just purchased a 325 sports tourer 52 plate with a genuine 43000 mls,any thoughts on fitting a k&n filter, is there any benefit or is it a waste of money. cheers

Hi mate, In my opinion it's a total waste of money. I have personal experience in k&n. I fitted a k&n induction kit which cost around £90 and it did nout. I would recommend hks
hope this helps

in all honesty mate you probably wont find any real gain as diesels normally flow pretty well anyway

Diesel? I thought the bmw 325i touring was a petrol?

First up I'd say improve the brakes, Z3 brakes should fit ok and you can get these from breakers yards nowadays.

Personally I'd drop in a panel filter if I were you. Induction kits with a cold air feed can make about 8bhp on these but I quite like the standard engine noise rather than the roar of an induction kit.

I know of a few guys that have dropped in the cams from the US spec M series into their 325's and these give a reasonable power gain. Another option is to replace the pistons and crank from the 328.

When you've done your mods get a remap done and this will fully realise the cars potential

Very late I know, but Simota do a highly rated induction kit.
