Blow Off Valves

This might sound like a daft question but !!!!

.

Having not owned a Zed before and just recently purchased one i am not to aware of what should be and shouldn,t be in the engine bay

 

at the front on either sides are HKS Super Blow Off Valves what are these and what do they do and I presume that i will have to let the insurance company know if they are a performance upgrade

    They rapidly relieve the pressure in the turbo's and make a great "Shhhhhhhhhhh" sound.

     

    You just saved yourself about £800.

     

    If for some reason you want to get rid of these I will gladly swap themover with my standard pipes for you at no chard (i'll even fit them for you ;) ).
