Hi Everyone,

Just got a 09 JCW this week, try to do some upgrade, first ting want to do is the air intake. I open the air box, it is a corn air filter instead of flat one.
Any recommendation on air filter to install with factory airbox? I heard K&N doesn't fit tho.

Any other mods you would do as well? Please show your mod list.
I am putting a JCW strut brace this week.

Thank you all in advance!

Steven

 

Check out the Pipercross air filter here as an option. ST coil overs are a great bang for your buck coil as well. Can check them out here. Do you just plan on daily driving the car or do you plan to do any type of track/autox days? You can cruise around our catalog here for some other upgrading options. Before I touched much on my motor, I completely upgraded my suspension/bushings. Powerflex bushings are great bushings to think about. These bushings are a great alternative to factory rubber bushings, which are more prone to wear, resulting in poor tracking and handling. And of course, a good rear sway bar is a good suspension upgrade as well. If you have any questions feel free to ask!

 

I have K&N on my '11. I heard someone say you get oil in the turbo which is stupid because there is oil in the turbo. hahaha. It's not much oil. It's just enough to pick up dirt. They fit perfectly. But I'd buy it direct from K&N.

 

Get you a factory replacement drop in dry air filter and skip the oil filtered ones. No issues with oiled ones so long as proper care is maintained. Less headache to worry about with a dry one though.

 

I'm partial to foam filters and like the ALTA one like this http://altaperformance.com/i-1400715...cw-intake.html

 

With an oiled filter the MAF sensor gets dirty with oil and becomes a problem, at least that's what happened to me

 

I bought the same JCW stage 1 CAI. I'm using the cone filter that came with it because I hear that it has plenty of air flow. When I get a replacement it'll be the AMSoil which is also dry and conical. I think the one we use is AMsoil # is 3570. No way I'd use an oiled filter.

I am debating between a dry panel filter or a cone dry filter. I have heard and read the panel filter has better air flow and that is why i think factory change from cone filter to a panel filter on the n18 engine, but i am not 100% sure.

 

Isn't that a JCW intake? The stage 1 air box is an option/upgrade on the JCW versions. I wouldn't think the flat panel would be any better. But anyway...I'll replace mine with the AMsoil conical when the time comes.

 

The N14 fJCW came with a panel filter as well. The cone filter was a part of the JCW upgrade kit that could be added later.

 

So n14 fjcw and n18 fjcw came with a cone filter? and later factory decided to eliminate the cone filter and leave the panel filter?

I have an R56 S with a JCW intake air box and inside there is a cone filter but i think and heard that you can use a panel filter as well with that air box, you only have to eliminate that tube that is inside of the air box and drop in the panel but I'm not sure about that because I have never done it before. ( is going to be my weekend proyect)

 

No, all fJCWs came with a panel filter. The airbox is identical to the one found in the "S".


The JCW airbox (equipped with a cone filter) you have is an optional accessory. You cannot fit a panel filter into that intake.

 

I see mmm.... so which intake is better or has better air flow? the fjcw air box with the panel filter or the jcw air box (optional accessory) equipped with a cone filter?

 

I would have to say with the JCW, being a Stage 1 option it would have to be better right??? I did so much to mine at the same time...intercooler, exhaust and Manic tune. I can't say for sure. I took the advice of Way @ WMW and that's the intake he runs on his GP. He also used the dry filter that comes with it. He says the airflow is adequate and wouldn't use an oiled filter.
