You're most likely not going to get an answer here because there are quite a few bolt in solutions available. So it isn't worth in for custom fab intercoolers. Do a search on the subject you will find alot of info.
That might be too big. Especially on the length. I have a Forge Twintercooler and I don't think it is that long. I'd have to measure when I get home.
You might be better off just getting a intercooler already made fort he car. If the Precision core gets anywhere near the price of a Forge twintercooler with everything you need to install (retail $850) or the S3 intercooler (I think they go for $400) your better off just buying one.
