Quick one - I have the choice of two induction kits and can only keep one...

Both have heatshields and the pipercross is newer. Which is the better piece of kit(both are effectively cone filters - neither has cold air feed).

Which looks nicer in the bay?.....

alternately, what's going to fetch more on The Bay? I'd imagine any BHP differences would be undetectable, so you might want to sell the one that would bring you more on eBay...

Keep the Apexi, sell the Pipercross. No real performance reason, just from my point of view the Apexi has more kudos attached to it.
Actually, list the Apexi as "JDM" on Ebay and then you can retire from the profit you make:lol:

LoL. The pipercross looks better... Job done. Can't judge on sound as my duals drown out any induction noise. I didn't want to make a schoolboy error and ditch the apexi if it had much better performance.

 

[5harp3y]

performance between to two will be marginal if at all.

keep the one that looks the best

Assuming the pipercross is a foam type I'd keep the Apexi as it offers far better filtration.

Keep the Apexi

Where do you get that from? just asking

foam is normally thought to be better from what ive been reading across the net.

Filters aren't just about airflow......hence the name filter

My brother is an AIS (Air Inductions Systems) designer of over 20yrs and has design air boxes, inlet manifolds and associated ducting for Aston Martin, Ford, Volvo, Jaguar, Range Rover etc... so I have a little insider info if you like.

Cotton filters (K&N, Green cotton, Apexi) offer the best filtration, paper is not far behind and is far cheaper hence all OE filters are paper, Foam offers the worst filtration but good flow, and as for stainless mesh well.... it's only good for straining your tea !

Interesting test and results. As interesting to see that the apexi is meant o be red. The one I have is well and truly black.

Well i knew - sorry, believed the hks style foam ones were rubbish and I saw a similar test lined on the FTO forum a few years back so I didnt rate the stainless ones.

Thanks for the link Jay.
The reviewer is floored there as the apexi will - like other filters become caked in crap and then will need to be cleaned or it wont flow anything.
How well does it work after cleaning - as if any of you have washed cotton - youll know the fibres deteriorate in the process.

Why didnt they test something good like an ITG?

Humm the more I read that article the more it clearly has an agenda - I read it with an open mind hoping to learn something.
However there is too much directed copy. No you should not "saturate" a K&N in oil - ohh but look one of the plus points of the Apexi is it isnt "saturated" and doesn't interfere with the maf. hummmm

either and agenda or an editorial going on there. Some things are a given but some of what is written there seem too convenient.

Still willing to learn but I dont trust the angle on that review.
Not doubting the wisdom on paper and cotton generally though.
