Hi,
About 3 years and less than 15,000 miles ago I bought a DiFatta air inlet hose for a 24v Alfa 164, 3.0 manual, 1994. It started showing signs of perishing within a year and began suspecting it had split. Ridiculous considering the original lasted 20 years before failing.
Today, having been donated a silicon air-inlet hose from another Alfa nut, I took the DiFatta item off and found it had split in two places, with imminent further splits on the way. How glad was I to have been given the replacement? Very!

Not only does this silicon item look really well made, the inner tract is also smoother than even the original Alfa item so should, I assume, help with airflow too. It is made of 4 layers on the AFM end and five on the throttle body end - flexible yet strong. The fit is perfect and have no doubt it will last for a long time. In fact, I liked it so much I asked my friend where he got it so could pass the info on here - maybe Jason would consider importing a batch for you guys in the States?

In any case, the guy's name is Michael Pasaric and he is based in Croatia.

My understanding is this is his speciality and, given the quality of the item I now have, he seems to be extremely good at it. Posting few pics - it's not on a car right now so just ask if you want more.

Well, that is interesting. Wonder if it is as flexible as the OEM? Might be interested. I have a new spare "in the bag" OEM S hose, but I think not for the LS (would have to check). Actually, I'm still running the S, LS, and Milano with the originals, as they have not failed. I do drench them in Armorall every couple of years. I think that stuff works for preserving rubber parts (evidently to reduce the outgassing of the plasticizer chemicals in the material). Time to do all the rubber/plastic parts in the cars again.

This one might be a good replacement for the LS, depending on price. Jason?

BTW, that cracked one looks really really old, all dried out. Maybe stored unprotected in a hot area for years.

Interesting. My hose does not have cracks but the material is stiff; wondering if the sealing at the joints is efficient. I will be looking at a rubber "shim" between the inlet hose and metal joint points. Then again, if you suspect yours may be getting ratty, you could spray the exterior with rubber coating?

My original Alfa hose went stiff before it split. Was also split for some time before I discovered it as the split was on the underside. If yours is still whole would make sense to spray it with some kind of rubber preserver/rejuvinator and avoid it splitting in the first place.

And Del, the perished one shown was not old at all. It was from a batch of replacement new parts made by DiFatta and looked perfect when it arrived, if a little thin rubber wise. To perish the way it did so quickly is simply an indicator of them using the wrong type of rubber in the first place. Looks like rubber that biodegrades - great for the environment, in theory, yet totally rubbish in practice as means doesn't last and a new item has to be manufactured.

With original Alfa items no longer available am glad to have found a well made silicon to replace the rubbish one.

Got it. A shame, as the difatta replacement looked good. I wonder what the silicon version costs?

Was total shame with the difatta item. Why go to all the expense of making the mould etc and then pour the wrong rubber into it?
The cost is about the same. My friend paid about £80 for the silicon unit so about $100? plus delivery/import costs? Am stripping down the top end/cam side of motor so going to be a while before all running again but will post comments when is.
