FAO Nicecupoftea Standard airbox

[DennisTheMenace]

here you go NCOT this is the standard airbox on the 1.8 , in this pic there are 3 bolts that hold it inplace 2x 13mm (m8)and 1 10mm (m6) 1st one is down by the headlight motor , 2nd is by the heatsink thingy (?) and the 3rd is by the intake up by the wing 10mm


there is a lug on the bottom this sits in a plate thats attached to the chassis leg by 2 13mm bolts underneath the airbox .

last bolt 13mm is behind the box between the airintake pipe and the airbox



HTH

Thanks!

That does make things a bit clearer - My airbox looks slightly different though.

I notice yours says "BPE8" while mine says "B61P" :scratchchin". I guess mine could be from a 1.6?

Fittings look the same though.

I am missing some of the bolts so will try to source them. Not exactly sure what you mean about the lug on the bottom - mine has a 10 mm hole and a couple of smaller ones either side - presumably ther's some sort of locating dowels on the car itself then.

How does the intake attach to the AMM? My intake has 4 bolt holes, and I have 4 threaded dowels but only 3 nuts (would need 8 to bolt to the AMM presumably, can't see on the car as it has a plastic cover over the cone filter).

Reckon I'll need to do a trial fitting at some stage when I have time...

Don't worry about differences in the "snorkel", It changed over the years. Earlier cars had a straight one like in that pic and later cars had a longer kind of 'S' shaped snorkel.

DTM - Are you sure the nuts are 13mm? That would be very unusual on a Japanese car. They usually avoid anything to do with 13. I know that I can pull just about every part off of my car with 10mm, 12mm and 14mm sockets and the only 13mm bolts are on the SC kit which comes from US.

lazza i will double check later .

is the Japanese not using 13mm bolts a superstition thing?

I know they are a bit like that in Toyota when I worked for them.

Hmmm,

Well, after driving my dad's Mk.2 1.8 150 miles yesterday and finding it altogether nippier than mine, whether off the mark or planting my foot at 70, decided it was time I replaced my air filter.

I have some Jap "Air Dancer" induction kit (basically a metal shield and a bit of plastic) and an Apexi cone filter.

Anyway, got it all out and came across a couple of problems. I have the same looking AMM as Dennis in the pic above, but there is no way that the round end of that is mating with the square bit of the airbox I have. Is my airbox from a 1.6?







Other thing is the hole at the bottom of the airbox - typically with my car all the bits that were not used when it was modified have been chucked out Reckon the other bolts will be enough to mount it strongly, so a couple of layers of gaffer tape over the hole??



Here's a pic of the filter. I doubt it has ever been cleaned and prob there since before it was imported in 98!!



Reckon it's worth sourcing a different airbox, or is there a way of cleaning the filter??

ETA: just realised I am missing the bloody exhaust manifold heat shield as well so I will just melt the airbox

You will need a heat-shield but it doesn't really matter at the moment as that's a 1.6 air-box you have there

[NiceCupOfTea]

Nuts :|

So, either I need:

• manifold heat shield for 1.8
• mounting bracket with locating pin for bottom of airbox
• 1.8 airbox (is it just the top bit that's different or the whole box?)

But I have an almost new K&N element! (as long as it's not different between the 1.6 & 1.8!)

Or I need to clean the cone filter or replace it....

How easy are they to clean? It's an Apexi Super Intake no idea if that's any good but it looks filthy (see above) and I can almost guarantee it's never been cleaned. I have heard horror stories about the oil destroying the thin wire in the AMM?

Here's the current induction setup FWIW:

I used to wash old foam elements in warm soapy water. Of course if you can get some access to compressed air iy's good to blow the filter out from the inside out before and after too, then a light spraying of filter oil. Note when doing this it's a good idea to wear goggles... (safety first!)

[MX-5 Lazza]

I use K&N filter cleaner & oil in my Halfords Special.

Why do you want to get rid of the setup you have?

[NiceCupOfTea]

I'm just not convinced it improves anything, and the filter is at least 10 year old and has never been cleaned. I'm not sure it even can be cleaned.

[MX-5 Lazza]

Is the shield just what can be seen in that pic or does any of it go under the filter to shield from the exhaust?

[NiceCupOfTea]

Yes, the plastic on the LH side bolts to a thin piece of aluminium which bends underneath and bolts to the car under the air filter, so there is some insulation from the engine heat. If I do leave a cone filter fitted permanently I will try to get a standard manifold heat shield in there too.

Have emailed all the MX-5 breakers on ebay but no reply yet. Really want to get it sorted this week...

[MX-5 Lazza]

I'd keep with what you have. It won't be any worse than a stock air-box and it looks distinctive
Either that or replace and sell it on MX-5 Nutz - someone there will pay good money for it

[NiceCupOfTea]

Would you replace the filter? What with?

I use this lot for all the bits I need to source for the MR2 - They are a spare parts matchmaker, and it works brilliantly http://www.1stchoice.co.uk/

Last time I needed a nearside front headlight was emailed by 12 different scrappies all offering the part at varying prices with varying warrenties. No crappy sales calls to deal with too. Worked a treat.

I wouldn't replace the filter alone - it'll clean up just fine. I'd either just clean it up and keep it or replace the lot. The choice is yours - stock airbox (works ok but quiet), K&N Filter-charger or similar (sounds good but does nothing for performance), JR CAI (looks good, sounds good and really works).

You could get an air-box from Autolink.

My choice would be to keep what you've got. Just fit an exhaust heat-shield. Someone on Nutz would probably pay good money for it though so if you fancy cashing in then sell it there. Does it have a makers name on it?

[NiceCupOfTea]

It's a "St.May Air Dancer"

I may keep it, just fitted it all back on as I need the car tonight and gave the filter a quick brush and compressed air spray (inside out). Not sure if it is clean though...

To be honest I can't hear any kind of induction noise from it all not sure what all the fuss is about on induction kits! However, I get bad fuel consumption so it could well be that the filter is clogged. Don't want to spend a lot of money on new stuff to find no difference at all...

[DennisTheMenace]

Im getting better MPG with the standard airbox back on , plus it takes cold air from up near the inner wing , not ideal but if thats what the mazda engineers came up with i will leave it at that.
