On my saph and every saph I have owned before every 1 has had a k&n cone filter fitted.
I hate the way they look and they don't fit well at all in the space the standard airbox takes up.
Been looking around and seen this http://www.randbmotorsport.co.uk/sho...?ProductID=143
I quite like it and may buy 1 but is it going to flow enough for my t35?
You can also choose 60 and 65mm outlets,any advantage going bigger and using a one off hose to reduce it fir my turbo?
Also like the look of the rs500 airbox but finding a good 1 may be difficult.
Anybody running 1 or any experience of 1??
You're view would be appreciated.

 

Proper 500 airboxes don't come up very often and are changing hands at over Ł500 these days.I sold one last year and I couldn't believe it went up to Ł400 on ebay.

I've a Pipercross foam filter on mine and it seems to fit better than the big K&N so might be worth looking at different styles of filter maybe too?

 

Cant remember what the difference is between 500 and std Cosworth air boxes are, I know there is but it escapes me

 

The base of the box is the same for all versions of the sierra, its just the lid thats a bit deeper on the 500 version and a larger outlet for the hose. They all use the same standard filter. Unless you need one for an original 500 just go for the aftermarket lid, its nicer and saves a few pennies

 

Another question,what power level does the standard lid become restrictive?
Say including a quality k&n or foam panel filter???

 

Tried my standard airbox on tonight and I have a problem,the pace intercooler outlet directs the hose towards the airbox inlet,possibly the samco hose may need cut down a bit where it comes out if the turbo?
I much prefer the look and fit of the standard airbox over the cone filter so I want to make it work.

 

I run an rs500 air box on my t34 saph, roose did me a hose to fit

 

Did you bung up the breather connection in the lid?
My car has an aftermarket breather so if I refitted the airbox it won't get anything on it.
I like that airbox lid.
Wonder how many kids there actually are floating about?

 

No not yet, going for mapping next week so will do it before that, I like the standard look but had one in the garage so thought I would use it

 

Cool,if you find another drop me a p.m 😜
