Hi guys I'm looking at buying a jetex cone filter, but not sure what size to buy, I was looking on eBay and the have one that is 80mm inside diamaiter or 70mm inside diamaiter? So which should I buy? Will I need a reducer?
If it's an A3, your MAF is 70mm, if it's an S3, your maf is 80mm.
If you intend to stick with a ko3 or ko3S on an A3, then stick with the 70mm filter. If you intend to upgrade beyond a ko3S in the future and hence a larger 80mm MAF, you could get the 80mm neck filter and use a reducer for now, thus future proofing the filter for further upgrades.
if it's an S3, then the 80mm filter goes straight on.
When I had a ko3S I ran an 80mm filter with a coupler and a reducer down to 70mm for my MAF, this pushed the filter further out into the inner wing as well. was a good setup.
I got my filter through today and so I fitted it this afternoon, I've been out for a drive but I'm not sure if it's me expecting things but the car feels a little flat when you put your foot down, but like I said I think it might be me thinking that, I also change the the turbo outlet pipe, but think I'm going to change that back to the oem one I took off. Can someone put some info for me?
I called r tech today and said that I had a cone filter, they said to take off and put a pipercross panel filter in, so now I have to sell a brand new jk cone filter, and put everything back on from the old box including the standard intake pipe work
grale1 ive got an agu engine with 80mm jetex cone with 70mm reducer going onto a silicone tip, also i bought a heatshield, didnt make alot of difference but it was noticable, its not until i remapped it and put on a 007p recirc valve that it all came to life. its swings and rounderbouts with cone vs airbox, for sound id say cone although since remap ive not used my old airbox. wait for a remap then decide. are you sure you have it sealed properly? any air leaking will make the engine a little sleepy....
Yeah it's sealed properly, I have the same as you 80mm with an 80mm by 100mm long aluminium coupler then the 80 to 70mm reducer, and I've put a 3 inche wide cold air feed from where the fog lights where going to the bottom of the filter, so it should be getting a good cold air feed but not working it feels very sluggish I want to get it remapped so we'll see
Think i found why my car with the filter on felt like it was going in reverse.. My filter has split where the coupler pipe I put through to be able to do the jubilee clip up has split half way around, £50 down the drain I think
all is not lost mate, how much doe u got spare?
insurance on mine is a joke, £470 with all mods declared and a ****** scooby was £490 and an evo £700 all full comp.
definately going back to jap now, cheaper running cost, cheap to mod and now obviously cheaper to insure.
