Hi I am just wondering if anyone can help me. I fitted a K&N cone filter on to my air intake senser and for some reason its not idling properly???

The cone filters are oiled, the oil can contaminate the MAF sensor

 

The crankcase breather connects to the filter, if its not re-connected properly it can draw air/ bypassing  the maf affecting tickover and general running

 

The original air intake draws cool air, and is designed to be a match for the engine, and often boosts low end/ midrange  power torque, a cone filter draws warm/ hot air from under the bonnet, and is not specifically "tuned"  to the engine - so you loose power - all it does is make more noise , and with the reduction of low-end midrange power, can  give the illusion of more top end - along with the noise - can make the car seem quicker  

 

On some cars (like high-output turbo cars or big v-6s etc ) a K&N (but encapsulated, wing mounted, or with a cool air feed) might work, on your car, you are probably better off with a stock airbox , in my opinion

Yeah fit the ORIGINAL airbox and fit a pipercross panel filter, this will A: increase your power buy 3bhp, not reduce it by 3 like the cone filter has. B: stop fouling up the maf sensor, and C: stop you looking like a !Removed! to all and sundry.

 

BTW chances are you've ruined your MAF sensor. These are over £100 for a new one BTW

 

Happy motoring

Haha I don't know where you have been looking for MAF sensors because there about 20-40 quid.

Quoting main dealer price pal!

 

My personal opinion is that anyone that fits a high flow cone filter to their car unless its forced induction and running silly amounts of boost, need a full frontal lobotomy.

 

No matter how many times Ive told and proven to people that they are shat, theres always some knob in a burberry cap that thinks otherwise.

Q!

- with a massive cool air inlet and a shroud, heatsheild and/ or vented bonnet

 

Ive never had a Burberry cap, do you think if i got one and put it on i would have this irational compulsion to go and buy a C**sa, slam it till its bottom is on the ground, and fit the biggest, silliest, loudest backbox i could find on

 

Dont tell anyone but ive got this massive K&N cone filter, i don't know what it was off  :lol:

I think your onto summat there. Its like a brainwash thing. All of em have Corsa's or low capacity saxos or fiesta, running on the bumps stops and the look koooonts!

 

I was a bit of a boy racer, but I had a s1 rs turbo with sensible mods, and then had a sapphire cossie sleeper with 500bhp! Looked stock from the outside! 

 

If ya gonna do it do it proper!

 

Have u ever been on barryboys website?? Some corkers on there!! LOL

I thought those cone filters worked best running straight off the exhaust gasses to make the most of the extra heat under the bonnet?

 

As for your new Corsa build, Halfords is best place to go really, I'd say get a nice big Ripspeed cone filter, and then have a pipe off the exhaust to divert some air over the air filter for a ram effect; the exhaust itself being about 4 inches, dual exit with 6 inch back boxes, straight through. What do you think?

 

Then have it 3mm from the ground for some nice handling, stretched tyres on some 18 inch bad boys, and about 8 degrees of camber front and back?
