Don't fit a filter?

I've found that they fitted in the metro k&n for hif38 as it has a centre hole but not fitted to the car yet I will be in the next few weeks and can let you know how it fits

I'm fitting MED Stub Stacks and K&N Pancake filters to my twins. It is going to cost me £210 altogether.

 

And yes, do fit a filter, you wouldn't believe the amount of rubbish/birds that would get sucked into your engine if not using a filter. Especially if it is a road car.

I have a stub stack on mine inside a Cone Filter but its not the one you link to its the one from Somfords Mini

Ahhh don't think so

Ramair. At least as good as itg. Added 3.5bhp to mine with a turner carb (med clone) stub over a k&n cone. See eBay then call them and tell them what carb you have.

Why not? Obviously I know why not but personally I think the positives outweigh the negatives, it's right at the back of the engine bay, how much cr*p really makes it up their?

Enough particles that is a very short while you'll be seeing blue smoke from the exhaust, you really cant run a road car without one.

[HarrysMini]

I'm sure I read about a guy who got a bird stuck in one of his open ram pipes once. It only needs to be microscopic particles to damage an engine.

 

You even said yourself you can't be too careful with engine hygiene.

In Vizard's book he mentioned running a car through a sealed track race and then emptying the contents of the air filter onto some paper. When he heated them to simulated being in the combustion chambers they turned into a paste similar to valve grinding paste.

K&N filters (according to his testing) pose no restriction to power, but save them getting full of grit.

Obviously you can't just wack one on and assume the engine's going to go better, they do need to be tuned and adjusted to the filter. A K&N with a stub stack or short velocity stack is the best option for power and filtering for an SU from his research.
