that particular intake manifold is fail as well - the stock one you have will be better

u could try reversing the piping - it my fit that way - otherwise you bought the wrong intake kit

just get a generic intake kit - most of the USDM d-series have slightly different heads to ours - and if your car is D16y4 than they dont even have that engine

buy a kit for 93+ D series - ie D15b7, D16z6, D16y1, D16y8, D16y5 - all of these models will work as they have the normal style intake manifold

a really nice sounding and easy to fit kit is the simota 'whale' intake - they are usually about $120 on ebay
