Quick question about air filters

Hello all,

Im a bit of a novice when it comes to cars but learning as i go. I own a 1.3 mk1 golf driver, and im interested in tidying up my engine bay and getting a K&N air filter to replace the massive flying saucer under my bonnet! I just wondered if there is anything i need to consider? For instance what do i do with the heater hose form the front of the engine block to the air intake? Any help is appriciated

Regards

the warm air feed is very important, without it you can suffer from carb icing and it'll conk out/loose power. you wont gain anything from loosing the round filter so i would just leave it alone. put the money into the 1.4 16v pot

thanks for the reply. Yea i will probably leave it, i just hate how big it is aha. Yea after a while when my insurance goes down im definitely going to look at more power! where can i buy a new pipe for the warm air feed, i've looked on the internet but maybe im not looking in the right places! mines a little tatty

iirc halfords used to do something suitable?

you could maybe look at adapting an SPI inlet to it, that will allow you to fit a gti look airbox on inner wing, though space is limited on mk1 so probably not so good. you could put cone filter on the spi inlet possibly as long as there is some kind of warm air control?

though to me its all a load of hassle for no real gain, save the money imo. if it was me as i say id be looking at 1.4 16v, or maybe a 1.4 abd lump out of a mk3 golf and fit mpi injection from a polo gt or later mk3 1.4

haha yea it does sound like more hassle than its worth! thanks for the help!

I've got a K&N in the standard housing in my driver - and it made next to no difference.

I've heard good things about the replacement ones, but as has already been mentioned, it'll ruin your running in anything other than a nice warm, dry day.

the 1.3 engines aren't really worth tuning, there's not really any power to be had out of them… I've got the K&N, a weber 34ICH carb, ashley 4-2-1 manifold, stainless backbox and skimmed cylinder head - and it's got just about the bhp it had when it came out of the factory.

If you want power, get a different engine, and if you want a reliable runaround, get a different engine.

the small block engines are great because they're properly revvy, mine doesn't sound happy until about 4,000rpm and the peak power is at 5,250rpm. but there's just no room for affordable tuning.

Think you should consider how easy you are making life for your insurance company! If a modification is apparent after an accident (even if the incident wasn't your fault!) they will duck out of, or reduce their cover on your car.
From your comments `Yea after a while when my insurance goes down` it's an issue with you already.
I seriously am NOT a spoilsport, I can introduce you at least one young man that had exactly this problem, cover refused for his car because of a large bore exhaust and alloys they weren't aware of!

Ok thank you all for the replies and help!

Hello all, I

I've had my mk1 gti (82) for 15 yrs daily drive almost mint, but i have a question? I think i know most but my mate also an enthusiast has a theary about air filters..i  just wondered if any of you might back him or dismiss him, I have a K&N air filter it needs a new lease of life with the products (k&N) he is not a fan and has advised to replace it with a standard one as the oiling of the K&N is not the best of the oil k-jet electronics inlet track. Any thoughts on this

Cheers all,

Chris

the std filters flow very well, there are various flow comparisons out there on other forums, toyotec has one on cgti.

some modern injection systems with maf dont like the k&n oil, but it wont have any effect on k-jet.

a bit of k&n oil wont make any difference when its already caked in engine oil from the breathers anyway. no electronics on a k-jet

Just as i though cheers john and well spotted i meant k-jetronic  

ah well, still no worries there as nothing inside the inlet that will be effected, the electricery bits on the k-jetronic  are outside of the metering head
