OEM paper filters will filter better than a K&N etc, been a lot of discussion on other forums re this, the test was performed by Phil Payne who fitted a k&N drove for 1000 miles took it and then wiped the throttle body with a clean white paper towel, pretty filthy. He then repeated the test with a stnd paper filter, 1000 miles later the paper towel was clean. Now the question is where is this extra dirt going and what will it do long term to your engine??

Yes but your missing the point of the cone filter, it flows alot more air than a stock filiter in the airbox. It's a tradeoff in efficiency of filtration vs air volume intake.

Better the filtration the less air will be allowed to flow. Hence why BHP figures can be increased with cone filters as the engine can get more air in quicker.

That's right mate

Have a read here

nice one

I am well aware of theory, and have in fact used K&N in the past, i now stick to paper for better filtration.

Wasn't there a filter test aired on the forum a couple of weeks ago? Showed quite clearly that HKS has very poor filtration whereas Apexi had excellent filtration and top flow characteristics. Would tend to prefer good filtration as a priority!

yup rotoboy posted a link above.

That'll be the one!

Still seems that there are conflicting opinions though...

Is that right, 200 quid?? I'm looking for a filter 'kit' to replace std. Was going to opt for the dahlback 180 degree bend etc kit. Does this include a filter or do you have to purchase one separately?

[AAH!]

The dahlback kit comes with a K&N cone filter....as it should for £190 ish.

[RustyNut]

Does that mean that if you want the Dahlback kit and an Apexi filter you need to fork out near on 400quid? The link Rotoryboy posted listed the Apexi at 200quid?

Does anyone know of an alternative kit similar to the dahlback one, with as good a heat sheild, less the filter?

Cheers

Dude, you can buy the pipewelds from ProSpeed, same chap who did my exhaust. You could easily knock up an equivalent heatshield to the Dahlback in a short time, it's a very simple design.

Then get a short length of silicon to fit to the MAF and the filter of choice.

Other option is to use two 90 degree silicon bends and join them together.

Well, because im skint and unable to make my own heatshield I went to Super and West tuners who put one together for me for £110 including a clever heatshield. Will post pics up later. They slapped a pipercross on it as it was the only one they had. But i guess i could of brought my own filter for them to fit.

only downside is he left fingermarks on the heashield which i will have to re-spray.
