Wanky induction kits, do they do anything?

[SiC]

Depends how fucked the plugs are when they came out.

[fordperv]

yes they make your car go bwaaarrrrppppp

[steveo3002]

dont even agree with the k&n panel filters , lots of tests online showing they dont do any better vs a paper one, and if they was so good how come most lairy factory made cars use a paper panel filter

 

spend the money on a good service or some decent tyres etc

[Dead_E23]

Yes.  You'll also need some of these magic tyre wear enhancing wonky badges.  

 

They are spelled 's-p-o-r-t' but pronounced the way you suggest above.

Because cars come from the factory bound by emission and noise laws and regulations.

 

Plus k&n* filters have a lifetime warranty unlike paper that needs changing every 8to12k so £40 a pop doesn't sound bad when you work out that a car with 120k on it will have had at least 11 filters @ £12 average.

 

 

 

 

 

*others are available.

on the other hand....

on a 607 the air goes in through a grill next to the front fog lamp (so quite low) and then get drawn up inside the bumper and wheel arch liner into the airbox intake which goes through a hole in the inner wing to above the wheel arch liner.

This is fine until you go into water too fast.

It gets scooped up by the low down entrance hole next the fog light and will (if you are going fast enough) splash all the way up to the air intake and hydraulic the engine.

I suspect that a cone filter will be less prone to this.

[robinmasters]

What? What's that? That's not an induction kit. That's a toy!

 THIS is an induction kit:

 

 

 

That red strap isn't a seatbelt; it's to tie your right arm the seat so it doesn't get sucked into the engine.

"based on our previous intake testing, the standard filter element in an un-touched intake system is responsible for only around 3 percent of the total restriction. A drop-in replacement won't make any noticeable difference."

 

Science and proper methodical testing bitches

[rainagain]

I'm embarrased to say I still have drilled holes in the standard air box in the past coz it sounds faster bruv

[PhillipM]

Leave your flies undone and you come out with a much bigger grin than expected.

[PhillipM]

Because cars come from the factory bound by emission and noise laws and regulations.

 

...because they don't filter as well, make no difference to performance, cost more and need maintenance instead of replacement - so it's cost you more money to do nothing but increase fleet costs and warranty comebacks.

[rovamota]

Recently spotted in a car park near me. Yet another Inappropriate use of the infamous Halfords universal 'sport' badge. Adds extra shiteness to any shite car and is also a waste of a fiver.

Unless you mount your cone filter low down behind the arch liner!

[Dead_E23]

The badge on that Toyota Spacio has been applied much too well to have any effect on performance.   

 

If it was to the right of the windscreen wiper or actually on the boot release, that would bounce off the rev limiter in every gear (1st and 2nd, anyway).

The problem with using any sort of oiled filter ( k&n etc) is that if your car has a hot wire airflow sensor the oil contaminates the sensor on a regular basis .

[SiC]

Iirc petrol VAG 1.8T are especially prone to their MAFs being killed by such thing.

 

A lot of intake systems - especially turbo cars, are highly optimised. You often see stuff going to no-where hanging off the intake system. They serve a purpose in ensuring the airflow is correctly flowing. I have seen first hand a 2008 Focus diesel running like crap with a k&n aftermarket filter, that was fixed by replacing it with the stock airbox.

 

With turbo cars, unless you're running heavily mapped on high boost, stock filter is sufficient. Even when it gets dirty, the boost control will just up the rate to meet boost demand. Only if its utterly clogged and fucked will even changing it make a difference to power. Will loose on economy though. Turbo cars especially suffer with oilled after market filters on their MAP sensors.

[twosmoke300]

I think I read that the std filter on a Saab 9-5 is good for over 400bhp !

[SiC]

I'd believe that! They're pretty enormous things surface area wise.

My series 1 Land Rover had an oil bath filter.  I'd soon have seen if it contaminated anything because the oil was black with filth.

[Split_Pin]

I've had one on my 1.8 Astra Coupe for 10 years, never bothered with a cold air feed, never had a problem.

 

It makes fuck all difference to anything though, you don't even get induction noise. I lost the original air box though and may have had to cut up the air feed to get it out in a fit of ignorance.

[Parky]

I would have thought red calipers and a Nurburgring sticker would unleash more horses

[Faker]

I used to love them when I was younger, but I've grown up now! I find I remove them now! You know..... so I don't look like a twat! My last purchase to have one fitted was my vectra gsi, and I went on line the moment I returned home from buying it... and bought a standard airbox.

[doobietoo]

Yesssssssss

[New POD]

My Accord needs a new air box and air filter (the current air box is warped and doesn't seal properly, and the air filter is grubby).

 

 

 

Again, sorry for such a boring, PH-esque thread.

 

 

This is autoshite so the recommended solution would/should include duct/duck tape to make it seal correctly.  I have experience of that on a mechanically fuel injected XR3i some/many moons ago.

 

If you think more flow will give you more power and torque, find a car in a breakers yard with a larger air filter box and make it fit your engine bay.  Or run without an air filter and see if you get more out of it.

[dieselassist]

ive a k&n one still knocking about here from when I put a 1.9TD AAZ into my caddy, till I sourced/found someone that'd sell me an airbox that'd fit ie; a mk2 jetta TD airbox, which cost €50, and I fitted that...

 

Ive lost the spray shiz that you have to spray on them cone filters - I found they regularly get blocked up as they are sposed to operate 'moist - you then wash them under the tap, which becomes a regular thing... and they are horrendously noisey when fitted to a diesel...

 

...cant you get the heat gun to the stock airbox to 'gently unwarp it' n get it sealing right??...then fit a stock airfilter??

[egg]

None of these mods are worth it if you fail to tell your insurer any get caught out!

[LostnotFound]

In the real world they should lower premiums. At best they make a lot of noise giving that dozy pedestrian chance to jump out of the way. At worst they reduce peoples mpg so much they won't be able to afford to drive as much - less miles equals less risk.

 

I do wish car insurers accepted a lot of mods as standard like some bike insurers seem to. It's almost as if it's get a clause, 'yes sir because you installed those rear parking sensors without telling us we will only pay statutory minimum out after you've been sideswipped by an eastern European artic on the m4'.

[Jim Bell]

You have an undisclosed non standard air filter. Im affaid we wont pay out now youve been knocked into a river by a 98 year old traveling on the wrong side of the road, though we sympathise with your situation.

For now I've taped the airbox up. Using a heat gun is a good idea actually, worth a try if it's only bound for the tip. I will stick a stock filter in, they cost all of £15 for a new VS £40 for a K and N one!
