Air Intake upgrade
- Thread starter Bazza
- Start date
DirtyDog yes it is, but as in my photo of the filter fitted if you want to use the extension you will have to make an adapter?
further to fitting this the fuel consumption has dropped a lot? so I think as the filter allows more air into the engine the ECU now pumps
more fuel to accommodate the increase in air? so my thoughts are that you don't get an increase in BHP but an in crease in fuel injected / used to allow for the air increase, I know there is a formula as to air to fuel ratio but I'm not sure what it is so be prepared to use more fuel?
I'm sure somebody will have another opinion? come on guys lets have it.

Looking at the pictures posted on here I guess all the engines are M44 or similar where the oem filter/housing is taken out and the cone style filter just just pushes on.
On my M43 engine I can remove the OEM filter and housing ok but there is also another pipe running from the airbox to the emission control air pump which also I guess needs a filter on it or some kind of adapter pipe to work.
Has anyone done this on a M43 engine?
Its the least of my worries at the moment ., but I do find it easier checking/working on the car without the huge air box in the way.

Sorry mate mine's a 2.8 so can't help but I'm sure somebody will be able to help
Is that unit that the small hose goes to an electric pump breather like the straight sixes had, if so you can ditch it altogether. They were only fitted for the USA market.

You have a MAF fitted together with O2 sensors, so your fuel air ratio is always kept at the correct ratio, so in theory more air equals more fuel which equals bigger bang which equals more power.DirtyDog yes it is, but as in my photo of the filter fitted if you want to use the extension you will have to make an adapter?

P.S the ratio is 14.7:1 for complete burn
Sounds like I was not far of the mark then
thanks guys
thanks guys
from my old M43 pippercross
home made heat shield on the pics but then a pro one installed later...cold air feed from the side of the headlight
@swamper .
Thanks for the pictures.
That's the way I was thinking of doing it as well with the small filter on the air pump rather than taking the airpump and all the electric sensors out, the way you have done it means if I have issues it will be a quick swop back to OEM
I do believe that on the M43 engines if you start removing the air pump it flags up codes which then have to be masked. I may well be wrong.
Its good to see someone has done it like that and caused no issues.
Thanks once again

Removing that smog pump won't give you any problems whatsoever. If it's the same as on my 2.0 there is an electrical connection for the motor and one vacc pipe which you plug up.

I wish it was that simple on the M43 Tony.
When I was over stacey and martins at the weekend we had a look at it. I think it's very different to the M44. Several pipes and sensors are attatched. When we did a search on the net to see how to do it it threw up several issues with code errors etc.
Ok, sorry my info no help mate. Hope you find a way round it.

I really appreciate you comments on this Tony, this forum is full of experienced people trying to help each other out.Ok, sorry my info no help mate. Hope you find a way round it.

I am going to do some more research as you may well be right in the end and its relatively easy to do
. How @swamper did it is probably the easiest way for the time being, then in the future when I have some miles in the car I can look at taking more out.
Will be interesting to know how you fare mate. Good luck and please keep us posted. In the meantime enjoy having your car.

Is it a simple remove Wayne? I think that's what's worrying him mate.

It's the Aux air pump which is worrying him mate, on my Z3 it was two bolts to dismount the pump, two nuts to remove the vac capsule off the head, blank that off, plug the vac pipe and disconnection electrical cable.
