LS 3 motor &kewlmetal front end intake problems

[keithsv8]

Converted front end to kewl metal on a LS3 motor, having a problem getting the intake tube air tight, the engine gives a o2 low voltage code eventually. Rebuilt the intake several times using different hardware and trying different things. I have it running way better than the dealer did after the conversion but its still not perfect. Has anyone else experienced this and what was the final fix????

One of my Canadian friends , Richard, built his own complete snorkel for the aircleaner so it flowed the same size all the way. He had to lower his radiator a bit but sure looked like it would work nice..
