The pcv port is a given cause of the size but I was unsure on the others. Thank you for the info Larry I appreciate your help. I have yet to download that calculator to my laptop and but I hope to shortly and may need your assistance if the offer still stands?
Hey Larry quick question off the topic of Q Jets but in another post somewhere you mentioned using NGK ur4 spark plugs I bought a set are these the ones you were talking about?
No, those are platinum plugs. In general, platinum plugs aren't the greatest in a performance application. these are the UR-4's https://www.rockauto.com/en/parts/ngk,6630,spark+plug,7212
I tried the bosch platinums once in my 430, and there wasn't much improvement. They seemed to foul quicker, too. I just have the stock AC plugs installed, and they've worked flawless in my engine for 10 years.
