Technical K&N vs Standard Air Box

[Trancendental]

Hi people's

I fitted my K&N ages ago and had my motor retuned so the Air/Fuel Mixture is good.

The K&N Sounds Great and is "meant" to give better performance.

Now either there is something else wrong with my car I don't know about or the K&N is actually sucking away my BHP.

Has anyone had any experience with replacement "performance" filters over the Original Equipminet one?

Thanks

i put a cinqi K&N on the tipo 1.4 fits perfect actually.. but doesnt actually give any performance increase.. just noise!

 

[custard]

do you have a cold feed going to the filter?if not it will draw in hotter less oxygen rich air.
not good for performance

 

[Bushboy]

why not just try the standard box back on? wont take long maybe ur k&N needs a clean

I got the old box (somewhere) but dont have a Filter (need a new one and if I'm goin to keep it might aswell buy a K&N replacement one)

Whats the best way to clean the cone filter and whats the best chemical to use?

Someone told me its good to rub it down with Diesel as it provides better airflow with added gas was told this by a mechanic who had a 1.6 Turbo Diesel Punto on almost 200,000 miles and it ran like a petrol with the economy of a Diesel... all it had was an Exhaust

Even with the Filter here will I still get excessiv hot air?

That looks like a dirty filter to me.....

Can't see that you would get hot air there though....

HOW TO CLEAN THE BASTARD!!!

 

[Bushboy]

you can get air filter cleaning fluid to do the job.. i dont know the exact chemical but you can get specific k&n stuff etc.. try ebay or google

 

[gregit]

I have seen it on many websites... failing that.... Halfrauds

Silicone spray cleans K&N's up a treat.

Why do you think you have lost power? If you have its unlikley its got anything to do with the filter. You wont suck in anymore hot air there than with the standard airbox.

In another thread you said you adjusted the distributer. make sure its in the correct position, i.e. the middle. If it is'nt its possible the rotor and cap wont be aligned well when it sparks causing a weak spark. its not very probable but possible.

I found this Info on the K&N lastnite but went to bed:

http://www.knfilters.com/clningins.htm

NEVER USE Automatic Transmission Fluid
NEVER USE Motor Oil NEVER USE Diesel Fuel NEVER USE WD-40, LPS, or other light weight oils.

The distributor was adjusted on my car a long time ago and put back as far as I'm aware. It was being experimented with at the time to solve another issue which was in the end, needed another cap. I'll try fiddling with it again. Its marked so I can always put it back to its original position

ive been cleaning filters for yrs by soap and water[k&n rec].once dry,lightly use the correct oil to make particles stick to it.job done.the standard air boxes on fiats generally flow well compared to say a ford.so unless the fueling and ignition is altered,the benefits are minute.on fords there is a difference due to there crap filter housings.

I tend to disagree on this from practical experience wasting a lot of time on the RR. I think 7lb ft on a Cinquecento Sporting is not just minute compared to the original box, which would be on a Tipo a bit more.

I cleaned my Filter with the Recharge kit.

I emailed K&N and asked:

Hi

I have recently obtained a K&N Filter for my Fiat Tipo 1.6. It is a Cone Filter not a panel Filter (take a look here http://www.tipo-onesix.pwp.blueyonder.co.uk/images/strut1.jpg)

I don’t know which Cone Filter it is I have installed but it does sound nice, however more importantly I am wondering what is the best application to use for performance needs, I have a feeling the cone filter I have fitted is giving me flat spots on acceleration but I am not mechanic and cannot really blame the filter but seeing as you are the experts in the field I thought I’d ask you.

Should I obtain one of your panel filters (33-2560) and go back to my original air box or is the cone filter I currently have more likely to suit my needs?

I’m not bothered about looks or how it sound’s, I want it to do what it says on the tin. More performance

Vehicle info:

Fiat Tipo 1.6 OHC 1992 (J)
Manual 5 speed
Petrol
No other performance mods (Exhaust System Soon to come)
Engine Number: 159A3000
Version: 160AZ55A

Thank you for your time

And they responded:

Hello
Thank you for your enquiry. The kit will give greater performance gains than a replacement panel filter. Re. the flat spot, it could be that the engine management system has not caught up with the extra air that the K&N provides. Disconnect the negative (-) battery lead for just over 30 mins. This should zero the ECU so that it starts a new learning curve.

Regards

I didn't think my ECU was that advanced, so in any case I unplugged it for 6 hours and then plugged it back in.

Does feel booty but then maybe I'm just imagining it

the improvement you are seeing there is when the cinq is properly setup.so even with the standard box with a K&N panel filter,there would be an improvement.

If you refer this to a K&N only, fair enough. But this does not apply to a proper induction kit. The way your post came over indiscated this referring to any induction.

well,not all proper induction kits work you know on all standard engines.it depends how strangled the engine was in standard form.to benefit from an induc kit,you need to change the engine characteristics.the exhaust needs to breathe freer.the fueling needs calibrating as does the ignition.just wacking on a kit is not the way to go.it will make an improvement on some,but not on others.

Developing induction kits is my daily business. I have not come accross any factory induction kit yet, where improvement was not possible. Presently I work on seven new kits for road cars, where one of them is considered as a real sports car and work on two race set-ups, which saw already quite an improvement. If you think you have a car that is standard so good that you can't improve on it noticeably, I invite you to bring it round. I am quite happy to be proven wrong.
