There are the grey ones which part no.: APS 05/01 and the black ones with part no.: SPA 05T.

Who has got experience with them (failures, lifetime, fuel consumption etc) and which one to choose?

 

Never heard of a SPA05T, old ones is as you say aps05/01. All newly manufactured ones reads SPA05/01 as far as I know.

 

I've got one here and it really says "SPA05T"..

But no difference in quality between the 'old' grey ones and the new 'blacks'?

 

Not that I know of but you better check that with a tuner who got long experience using both.

 

Both are the same there was a manufacturing issue with em think thats why there now black /dark grey ish

Do you remember a year or so ago they were £95 cos of this

 

SPA05T = never heard of it.

Andreas's part number is correct.

 

Oeps... and if Stu doesn't know..
I double checked and this is what it really says. With the capital 'T'. First I thought maybe the paint from the characters was fading, but no.

See pictures, sorry for the quality, the camera doesn't has manual focus.. but the capital 'T' can be seen.

 

APS05/01 is on mine and thats a dark grey colour..

 

YBJ is that the one that i sold you?

i never noticed that if it's any consolation, i've been using it for about 3 or 4 years and my car always used to drive alright.
