Description:

Relocating the intercooler reservoir and mounting the pod filter in the inner guard. Making a cold air induction system using the passengers side lower vent feeding 125mm duct into the pod filter.

Purpose:

To relocate the air filter so that it is not in the engine bay and drawing hot air. It will be relocated to where the intercooler spray reservoir use to be. The intercooler spray reservoir will be relocated using an APS made unit.

In theory the pod filter will be drawing in plenty of cold air from the lower air damn and this should create better intake temperatures.

Parts Needed:

* Pod Filter (pref stainless steel)
* Alloy pipe 76mm
* 76mm Straight Silicon Joiners
* 76mm 90 Degree Silicon Joiner

Cold Air Intake:

A Friend
Wide air intake
125mm Round Duct joiner
1.5m x 125mm Duct
Duct tape
Cable ties
Custom mounting brackets
Black Spray can

Parts Cost ~ $190
Estimated time to be used: 4hrs

I will list instructions once i have completed it.
ETC: This weekend ~7th Feb 2010

looks cool... but i still think that without a fully enclosed box u will have two problems

1) cops will defect ya as an open air filter
2) hot air will be comming in as 180* of the cone filter is open and not close to the filter.

btw i dont see a MAF there? what ecu u running???

You might want to consuder getting a hard type plastic duct.
Stone chip will easily destroy that foil type duct.

The air pod will sit in the inner guard.. it wont be in the engine bay compartment and the air filter is not an oiled element so it is a ok.!
There will be a piece of alluminium sheet metal covering the hole where the intercooler reservoir use to sit so it will have a 3' hole cut into for the air filter piping to go into so it will be pretty much enclosed from the hot air the engine bay is creating!
The duct will feed directly to the pod filter! Not to mention that the vent compartment will act as an enclosed box only drawing cold air!!!!

In theory it should work wonders!

I had severe engine cut outs when I first got mine because the element wire in the air box was a slightly dirty. The car would jolt, shudder and struggle to idle.

I ended up fixing it by cleaning the wire with spray from Autobarn for $15, after which it purred like a kitty.

Does anything special have to happen when replacing the original air box? Doesnt it plug into the engine management or something from memory?

thats only the air flow meter which is removable from the air box itself so you can fit up a pod or cold air box. i think jons has a motec so it doesnt need the airflow meter as it runs a map sensor instead.

my car is the same and so is dans with the aftermarket ecus we run you dont need the airflow meter anymore

if you have put the filter behind the duct in the front bar, where cold air is already going straight through, what's the point of making the ducting pipe? it wouldnt really be achieving anything would it?

rotfl... u can buy 3M CF wrap... that should get u to the required 200 depending on who u get it off :)

maybe thats why he only posted it here. there is a similar one on evooz, but i think johns better as he made a proper air collector..... i presume that the cone filter lives under the AL plate.

I think it will achieve more then just plonking the filter into inner guard. For start you will not beable to see the air filter because the vent/duct is hiding it. And secondly it diverts ALL the air from that vent into 1 spot where the filter sits so your getting 100% air from the vent instead of say maybe just 70% cos its just sitting there.

yerp thats correct, theres going to be an alloy plate that will sit ontop of the rail/behind the headlights.. with a 3' hole in it.. so when you look into the engine bay you cannot see the filter either and plus it will enclose the inner guard so its like a 'box'

this is what it currently looks like.. as you can see its still a good ram air feed for where my pod is atm.. however that will all change once it goes down to trikfab to get an alloy plate to cover the hole with a 3' hole for the alloy pipe to feed into.. obviously the pod will be hanging off the pipe.. so nothing to see :)
