Installed as&m headers yesturday, and the AIR fittings are bigger than my stock fittings, I found a website that showed which to use and i lost the website!!! Does anyone have the website or know which size fittings i need? I remmember reading somehting about 22x1.5 or 18.15 threading but i need that website!

Also, is it possible to get all four spark plugs in on pasenger side without unbolting the header? I tightened everything up thinking i would be able to get them in and realized i might be unbolting them again.... Let me know

Thanks
