Afm

[coco69]

hey guys,

i read it heaps and stuff - and i know most pplz will say to just do a search.

but i kinda get conflicting ideas.

whats the best way to diy clean the AFM?

- some ppl say not to use wd40 as it coats

- others say to use CRC contact cleaner or carby cleaner, others say not to?

- i read that you should spray when engine is on? wtf? coz something like it heats the element at the same time?

also, i understand its beneficial to remove the rear meshing (one closest to the turbz.

cheers, sorry about the 5000th post on this topic.

you MUST remove the afm and then clean it. i used carby cleaner and left both meshes in and all is good. hope this helps.

[coco69]

so just spray some carby cleaner into the element?

yeah

remove, spray, let dry, replace!

ps how did your biomed exams go??

Only SOME people say not to use WD40?! Jeebus man, who have you been speaking to?

Does anyone know if the AFM from the S1 R33 differs from the AFM in the S2. I have just had my airbox/AFM out to clean it and apparently it looks substantially different to my friends S2 AFM.

It has a green plate on it on the bottom of the unit and seems to have a plastic shroud around two elements in the middle.

Aparently my friends S2 has only a single wire?

I think electrical contact cleaner works best as it leaves no residue. I have heard brake cleaner to be good as well (no residue) and that carby cleaner works but leaves some residue. But don’t use WD-40 as it would contaminate the AFM rather than clean it.

I don’t think this will help too much sewid but in my 95 R33 series 1 it has two elements and a pink identification plate. One part of the element looks like a tiny resistor and the other is a flat white plate. What worries me is there is no mesh on either side of the AFM, it looks like the previous owner has removed them. I think it is fine for the mesh facing the turbo to be removed but not entirely sure of the ramifications of removing the mesh facing the air filter. I heard its better to keep the mesh facing the air filter as it changes the character of the air flow for a more accurate reading. Does anyone know if this is true and of any problems with both being removed? I have to wonder why they were both removed, possibly to reduce restrictions?

Yeah there should be two mesh pieces. I have removed the one after the AFM but left the one facing the air filter on.

Your AFM sounds like my friends S2 AFM (pink plate). Does the element assembly/plastic part go all the way accross the pipe? Mine only goes 2/3rds of the way accross.

yeah killer exams... 3rd year is soooo much harder than second year

what elective are you doing?

[Silver-Arrowz]

I've cleaned with electrical contact cleaner. No problems.

[Guest RedLineGTR]

coco we talked about this before...gimmie the money i will buy it for ya and do it for ya if ya want or show you how to do it...dont be scared..

You can pop it in the dishwasher if you want....lolz..cleans it real well...lolz

Don't worry about the meshes.. mine have always been removed, makes no difference. Leaving them in is more likely to cause a restriction than not having them at all.

Yeah sewid, mine is like your friends with the element plastic piece going all the way accross the pipe. My late model series 1 33 might have some series 2 parts in it.
