It told how to read the date on the upper intake. It also said it may be helpful in determining if it had been replaced.
I read the code on my intake and it is as follows: 01-19-11, reading from right to left as the link said. What does this tell me, am I in more or less danger of the intake failing?
Tim, that tells you that you have the original UIM in your car. Depending on the miles you have already, it could mean you should keep a close eye on your coolant and engine performance.
Gojo83, per your replacement grading request. Which replacement you choose will be a judgement call. The Dillon UIMs are roughly $60 IIRC and are "remanufactured" from UIMS removed after failure. They are then sleeved and I believe the coolant passages are plugged. The sleeving/plugging should prevent any further failure due to coolant passage breakdown.
Then there is the APN UIM kit. It is all new manufacture and also includes sleeving, though not with as much air gap as the Dillon ones. These appear to be a very good kit for the money.
The Dorman UIM kit is getting to be a better and better deal, depending on how old the Dorman stock is where you get yours. What I mean by this is; Dorman has begun adding multiple choice sleeves for any year S2 LIM fit, plus they are including all the seals and o-rings necessary to do the job, and the coolant elbow. Their price has gone down to meet the market too, with the last price I saw at @ $140. Dorman has also added extra material to their UIM in an attempt to make it last. The Dorman stovepipe sleeving has improved recently also.
Others can comment or offer their opinions as to which is the best choice for you.
