Hi again,

Ok, guess ill have to suffer it.. I drove the car straight after we fitted it, and it seemed to start 1st time with no trouble. I will give it a go tommorow morning (from cold) and see what happens. Do you reccomend that i leave it open then? As i was considering trying to cover it.

Thanks again,
Rich

I recommend you keeping the standard filter for winter. I learnt the hard way - took about 30mins running the k&n until my carb froze and left me stranded all of a sudden in traffic when the car stopped.

Hi again,

Ok i have kept the old filter in the boot, just incase of any problems. I have a 1994 m-reg, which is the single point injection model as ive been told by many a person. Would this still suffer from the carb freeze as u mention?

Thanks,
Rich

PS. I currently have something blocking that hole up (as mentioned before) so do you think i should keep it blocked, or leave it open?

As concerns your engine - if its single point injection as you say it won't have a carb.

For the hole, i'd personally keep it opened - but i don't think it makes much difference whether its open or not.

Thanks very much, and thanks for all the information you lot have given me.

Started it yesterday morning and it fired up first time, seems to be ok, and im guessing its ok due to the fact its single point injection.

Now to get the exhaust fitted :Q

Cheers,
Rich

Ye need to block off the pipe coming from the carb that used to be connected to the underside of the standard filter. If your unsure what one it is, test it by putting your thumb over the end of the pipe when the engine is running and the revs should drop to a more resonable value.

Hi guys,

After having a few problems with the fez it is now back on the road. Becuase of this, I decided to put my K&N filter back on for a bit of noise :)

So just a quick general question for the experts out their.

Basically, when I fitted the filter on, I was also sent one of the little oil breather filters. Becuase of this, I understood that I didnt need to drill the plate of the K&N and feed a pipe through it, like a normal installation would have??

Anyway...... I noticed that after the filter was fitted on and I started the engine that their was a fair bit of white smoke coming from the oil breather. I was told that these fumes are probably created with the standard airbox, except they arent seen or noticed becuase they are recylced in the back into it? So, my question is.. Is this the case? Or have I got a problem somewhere along the line?

Just so you guys know, almost all the smoke does clear away after the engine has been running for 2-3minutes and I have also driven it on a couple of longish journeys with no problems.

Never the less, any answers would be helpful..

Cheers,
Rich

hi guys, just a quick question.

i have a mk4 escort 1.3 carb. when i fitted my k&n and a little breather filter my car seems somewhat sluggish, doesent want to go anywhere. im guessing this is down to to much air goin in and not enough petrol, how can i sort this out? cheers in advance, mike.

I tryed a small breather filter on my oil cap, but when your driving the car, the fumes just come in throught the air vents, how can i stop this happening.

hi sorry for bringing an old post back up, i have a bolt on filer on my 1litre carb engine and to be honest i didnt think much to it even with the carb tweeked and ive reverted back to the standard air box, so my question is, would the K&N replacment filter that they product that fits in the standard air box be worth it?

Common problem. The engine is supposed to ingest it and burn it up, therefore it's not noticed with the normal air box until the element is replaced and the oil is all over the inside of the air box. Only way around it is to put a pipe on the filler cap and run it down to the bottom of the engine bay.

All i did was pipe the breather from the rocker cover into the k&n base plate with a 90 degree elbow and its sorted. I get the odd drip of oil on the inlet manifold but i can live with that

This thread only mentions the 1.1 and 1.3 HCS engines.

Will this K&N fit on my 1.0 HCS engine?
