I'm looking at getting a new air filter, possibly the K&N 57i from MiniSport. I'm wondering if anyone has any advice as to fitting, or generally if they're any good. Or, in fact, if the Pipercross is any better... I have a One, and I'd like to maximise it's power really.
Yeah common problem that. Even the genuine JCW filter does that
Had my soundproofing replaced under warranty and the filter finely adjusted and now it doesn't do it.
You will probably find you'll lose power with the induction kit on the One. On a rolling orad day I attended a couple of years ago. The most powerful One was the standard one! Those with aftermarket induction and exhausts all lost power. None had any remaps though which could explain it.
Agreed. And I had to take my sound proofing off due to my OMP strut brace and Pipercross filter. I am sure it will all fit but it was just a tad too tight...so I thought it would be better to remove it.

The 57i is an induction kit, not a Cold Air Intake (CAI)....thats why some Coopers and ONEs running it and similar products develop less power than a stock or replacement panel filter car. The 57i has the problem that it can pull bigger airflow, but that air is not nessesarily cold! The air its pulling in is the air in the engine bay...therefore its warm...which will not enhance power it will deminish it because the engines burn is less efficient. My advice go for a sheilded intake...the Piper Viper has a degree of sheilding so it performs better than most....plus I think it has a direct feed from an external air source, rather than the stale air in the engine compartment.....but CAI like the minimania one I believe are best on the ONE/Cooper.
My advice is steer clkear of open cone filters that are not shielded or have a direct feed from the outside/cold air! Buy a sheilded CAI, more expensive but will give you power not lose it! The alternative is to fit a panel filter like K&N or Piper etc and then use a replacement pipe for the inlet pipe...choose a smooth silicane style rather than the corrugated type used by the MINI as standard. This will give imporved flow (sheilded from some warm air by the standard box) and feed air in a nice smooth flow through the smooth silcone pipe....creating less turbulance on the air flowing into the intake on the engine.
