I saw a Euro R primary section and was wondering if it is any different from the stock H22 primaries? my guess is that the primary characteristics are the same but it is a little different because of the clearances in the accord? ????

 

never really looked at one, but I heard that they are pretty different than a stock h22 and that's why people liek to use them more for more N/A power

 

Euro IM is a single stage manifold. USDM H22 is dual stage (secondary runners open at high RPM to help with top end power). Having only one set of runners helps with making more consistent midrange power

If they're like the Type-S primaries they might be bored out a bit, but that should be it. I doubt they're any different for the Accord.
