Anybody know ID of the Alta intercooler hose couplers it looks like it is 4.5 ?

Thanks Bob

 

Come on kids someone must know ��

 

Most of R53 owners are not kids, but I would take that as a compliment. I have bought a couple of Alta products. I do like their rear sway bar. From my research of other R5X owners' that have much more miles than me, the only reason to go with aftermarket SC coupler boots is if you like the neon color bling, or you have an intercooler that the factory boots do not fit.

Just search for the problems with aftermarket intercooler boot problems. Most are just overpriced silicone hose cut to size, unlike the OEM boots that is purpose made.

 

WOW ! Wrong side of the bed ? Thanks for all the none help.

Have a nice day ��

 

I can measure my stock boots tomorrow, I'm sure they have to be roughly the same ID to fit.

Edit: Totally forgot to measure! I'll try to remember tonight.
