Im changing the vavle stem seals on my b16a in my crx. I bought a felpro kit and I noticed they are all the same color. I know other brands have them marked for intake and exhaust. so im not sure if they are all the same.

 

The valve seals on all b series vtec motors are the same the intake and exhaust seals are all the same.

 

I know for a fact oem seals are different and have a different color spring to help identify. As mentioned above, many aftermarket brands are a one style fits all
