think of the £££

Say you do 20,000 miles a year, at a change of filter every 10K at how much? thats 2 per year.... ppl on average keep there car 3-5 years.

Filter = £10 x 2 (per year) = £20

Keep the car for 5 years = £100

£100 on air filters

By a Performance life time filter = £35 + £10 Cleaning kit

the Kits tend to last 5 cleans or so, if you do this on the Basis that you are doing it every 10K (2 a year) = 2.5 years x by 2 = 5 years = 2 cleaning kits.

Total £55 for 5 years..........

£55 on air filters

They are not proven to give a 'Power gain' and no - one has ever said it has reduced air flow. Which one do you prefer?

You forgot to add the extra time required for cleaning, drying and re-oiling (if required) and drying again over the OE solution of chuck away old filter, clean housing out (which should be done with any filter change/clean), and insert new filter.

You also have the added benefit of not sounding like the chav round the corner in his souped up Saxo/Corsa etc with loads of induction noise .

For me, whilst an OE filter will do the job i need it to without restricting the output of the engine i'll stick with them .

Don't forget any 'performance' air filter is also declarable to your insurance company - whether it will incur an excess will depend on your insurance company (some wont let you do ANY mods).

Shoulden't oil a diesel filter

But when it comes to cars.... we do this as a hobby...... and that time does not cost money.

ohhhh your talking about an Induction Kit!

Im talking about a performance panel filter, these create no extra induction noise..........

Think you will find the panel filter also create extra induction noise too. (going by what others on here have said)

K&N on a smart car = no extra induction nose

Green on a Fabia Vrs = No Extra noise

my Pipercross panel on a fabia = no extra induction noise.

Moffball (barley posts) has a cone who has Major induction noise

As we discovered from the confusion between us, we don't know if people with this extra noise are talking about panel or cone.......

They don't make any more noise anyone who says they do are wrong!

until i see proven back to back dyno runs comparing oem to performance these claims are worthless. Also K&N in their own literature state their filter do not filter as well as oem - look for it on their website if you want.

So I keep mine standard. But if you want to run K&N etc its your car and your call, just don't go recommending to others when their is no proven advantage.

I changed mine whilst on a Rolling Road at Motorscope in Northallerton last year.

Dirty OEM (approx 18k miles) = 142.1 Bhp @ 3824 rpm - 248.2 lbft @ 2109 rpm

K&N Panel = 143.3 Bhp @ 3838 rpm - 249.9 lbft @ 2116 rpm

So I gained 1.1 Bhp (0.85%) and 1.7 lbft (0.68%). However I was told it would slightly increase when the ECU adapts over time.

BOOM! just like that!

Nice one Jim

All you have actually proved is that a dirty (your words) filter will actually hold the car back from producing it's full potential, whether it be an OE or 'performance' filter.

Do you know , I have to say , it is people like you that keep me coming on here after a long day at work

As you make me laugh.....thank you

Sarah

i know a lot of people will beg to differ, but in my opinion performance filters are a complete waste of time and money

you can't really compare a dirty oem filter to a sparkling new performance one, i'd like to see a new oem one tested back to back with the 'performance' one... besides in 99% of cases it's not the filter that causes the restriction, it's the airbox itself..

For some reason I kept the old filter. I have found it and taken pics of it with my phone.

Probably not the best pics to show the muck.

Edited 24 August, 201015 yr by Jim H

thanks for the post Jim, honestly surprised! But as others have said your oem was dirty. Also the performance increase was miniscule and I wouldn't be happy with a K&N which does not filter as well as an oem one. But likefolks say you pays your money and you takes your choice.

personally i went for a k&n 57i kit as i sold my pd160 and panel filter for 20quid more then the induction kit lol, and it gives a nice wistle and note, performance increase with this mods are negiable as saId but for noise i feel its worth it alone, i like people hearing the tractor coming

Well, im newbie with this stuffs.. im just wondering, what is the difference between buying the induction kit, or just the filter? Both giving the noice right? and the performance, well its so small with both of those that i wouldnt feel a thing

I think they are a load of tosh for diesels though as diesels by definition run with an excess of air.

What causes soot is the fact that the revs go up high enough that the fuel in the chamber can't burn quickly enough before being stuck out of the exhaust.

The soot you see when the turbo cuts in is often just the soot that's sat in the exhaust being kicked out and that that isn't is again just too much fuel to burn in the time.

In a derv excessive fuel will actually lower the temperature, quenching the explosion and so reducing the effectiveness of combustion past a point.

i noticed a little extra noise on my suzuki swift sport with sport panel either pipercross or monster can't remember which but in the end settled with bmc cold feed carbon fibe(old feedr theres also a slot in spotlight for the cold feed tube(just watch out for puddles)

i know pipercross do an induction and a vipercross for the 1.4 8v si i've seen at which 80 is reasonable (racemodz in urmston have always fitted stuff cheap if they supply induction) and 250<a lot to pay

Its really not Warwick

Not that I can comment on the effect vs OEM on My current (vRS) and last (2.0 8v) Fabia as I never ran them with the OEM one - just a K&N one BUT I did feel a deffinate difference when I changed over to a K&N one (from OEM) in my first car - a 1.3 LXI Felica. I remember the day well.. it was raining and the roads were quite wet and I remember that before I fitted it I couldn't get wheel spin in 2nd gear (P6000 165/60/r13) when pulling off a roundabout etc but after I fitted the K&N it was wheel spin galore (in 2nd) if I wasn't careful! It deffo made a difference to the BHP/torque/engine breathing and to the day I have swore by them and always made sure the car I drove had one in!

It probably started wheel spinning because the roads were wet.

I've spent a lot of time looking at the best filters on my old tuned classic mini engines, from just ram pipes with no filter to the standard filter. And most the time with a better filter, you are loosing low down torque. Then gaining about 1 or 2bhp at the very top of the rev range, and that was on 130bhp a-series race engines. Similar story with exhausts really.

What about oil deposits on the MAF sensor wire?

Just fitted a BMC panel filter to my VRS after having replaced the old one with a OEM filter a week ago, and throttle response has improved, and the BMC fits better in the airbox than the OEM one. It's also nice to know you're getting equal flow on the performance filter, rather than worrying about decreasing flow on the OEM in 10,000 miles. It also only cost £42.50 and the build quality is lovely, and you get some nice BMC stickers too! lol

and how often do you need to clean it and how much is the cleaning kit and etc etc etc

Oh , but then the guy is happy

He has a bit better throttle responce

Why is he wrong??????

you pays yoour money , you make your choice

He spent his money , he is happy

is that not what it is about????

what washing machine do you run?

i am sure I could diss it

But it is not about that

It works , it does its job

So does his air filter

Good quality , extra throttle , not too expensive

What else would you like????

Thank you Sarah
