UK-POLOS.NET - THE VW Polo Forum

Hi all,
I’m toying with the idea of a intake on my stock 2015 polo GTI and have come across some issues identifying the correct name for the factory turbo.
Here’s what I’m after ( as per golf 7 )
1 - a larger turbo elbow and silicone hose
2 - a enclosed air filter
3 - turbo muffler delete

I’ve been looking at the revo and racing line stuff, I’ve contacted a couple of companies who all quote me the same guff listed online which is ‘ it fits a IS20 and IS38 turbo’

Can anyone tell me what turbo the polo has from factory? I see IHI cast into the housing ?

Am I right in thinking the IS38 is for Golf R and the IS20 is for golf GTI ? Is the polo GTI turbo an IS12 ?

Thanks in advance.

Hi

I've fitted the racingline intake on my 2015 gti but wasn't happy with small elbow fitted stock.

So looking into it i found that all the turbos have exactly the same dimensions for attaching everything.

So a racing line elbow fits no problem but you need the breather hose off a golf R as it attaches to the underside of the elbow rather than the top side.

This also goes for muffler delete fitting any turbo is12,20,38

Thanks dink,

That’s pretty much the answer I was looking for, so just to be completely clear I can order a polo specific air intake and golf mk7 specific elbow and turbo muffler delete ?

How do you find the racingline intake noise wise ? Good, bad or ?

Many thanks again.

no if you get a polo specific intake it will probably only fit the smaller elbow

racing line do a kit that comes on top of the intake but imho it's pointless as you are left with a useless silicone hose

that is why i fitted my own silicone hose to the racing line elbow

you will need the breather unless you find a larger elbow specific for the polo

I didn't get it for noise so can't comment plus i wouldn't hear it over the milltek

Thanks yeah you’re right about the air filter to elbow pipe.
I am aware that i will be buying a pipe that will not fit and never be used.
By chance do you know the part number for the golf breather hose required?

This is the pipe but if you buy the racingline upgrade i believe it comes with it.
