Hello,finally took my courage and trusted my mechanic skill (woooo) and i installed the short ram from Cosmo in my vibe. Went pretty good (thank K&N for your Typhoon instruction! cuz Cosmo one are a bit short for a 0-skill like me! ). Anyway, no cel, good sound and a little performance gain so pretty happy for a 100$ upgrade Had a question, for what K&N instruction call the Vacuum switching valve (point 19 of there instruction). Has you can see the valve are now simply open without anything to protect them. I was wondering if i should put a little rubber cap on each of them or not..? Anyone did something about that or simply go by the: if it's not broken dont fix it!
