Cleaning a Pipercross Induction Kit

Andy G · Post by **Andy G** » Tue May 16, 2006 10:48 pm

Seeing as this has now been taken out of my 111R, though i should clean it.

Anyone got any thoughts on the best way to do this.....till hopefully it gets re-fitted!

Soapy water and re-oil it

Halfrauds about £10 for a K&N kit but thats cotton gauze (Like my hurricane) assme its similar for foam

Should've had instructions, they don't all use oil. Actually, I seem to remember Phil telling me something about scooby's having problems with induction kits that used oil on them. What was that again Phil?

A guy at work told me it screws up the mass airflow sensor ( Think thats what he called it ). I mentioned I had oiled my Hurricane .

AFAIK, they should all be oiled, unless somewhere it specifically tells you not to.

The cell structure in foam is nowhere near dense enough to catch dust particles, it needs the oil to do that. Certainly, I've seen pipercross oiling kits before and I don't think they do any cotton filters.

Shows dirt retention oil - perhaps the K&N stuff is the wrong formulation, but they definately need oiled.

Avoid doing it and you'll end up with valve stem seals like this:

Hurricaines DO need regular cleaning and re-oiling - he may be talking some form of truth for scoobys, but not for this engine (K series).

Worth checking out for the 'Yota, mind you....

Which ones don't mate? I've never seen them.

Hmmm....

The last three posts may indicate that I'm a bit heavy on this... For a reason - dust ingestion is a major part of what killed my engine.

The only filters I know of that don't need oiling are OEM restrictive paper filters. Cotton (K&N, Hurricaine, etc) and foam (Pipercross, etc) are just a suspension medium for the oil to catch particles - the material keeps out rocks and stones, but that's about it! It's the oil that does the filtration, which is why you need to clean and re-oil them regularly (once a year at the absolute minimum - much more regularly, if you're on back roads a lot - every week, if you're tut!) When the oil gets dirty and loaded up with grit, it's retention qualities drop off markedly and it starts letting grinding paste into your valuable engine - K&N's lifetime guarantee only applies with regular maintenance.

I will be doing my Hurricane every two thousand miles as I pulled it the other day for a look . I expected it to be fine and but it was heavily contaminated. My slightly fluctuating idle has since cured its self.

Yup - filters like the Hurricaine which use closed cold air scoops are particularly bad for this - surprised small rodents and children didn't fall out when you took it off (you can find the oddest things in there!)

Do you think this might be part of the TPS reading issue? i.e. the thing needs serviced? Have probably done about 7-10k miles without showing it any love

Wouldn't discount it. Esp if what the Scooby boys say about their MAF sensors are true..

Just to add to this - Tut once left his filter on the Honda for the thick end of a year without cleaning and ended up losing 50bhp on a rolling road day!

Although, i did hear that it looked like an elephant with the sh*ts had used it as a buttplug.....
