Clio 182 & C5 VTX+
Fitted the viper last week with the cold air feed connected. Tried it for one week and found that I had lost that nice 5k punch, it was still there but not as it used to be. Read a few posts on here about air flow so disconnected cold air feed and fed both original air feeds to the front of the open ended filter. What a difference. 5k punch back, more response at low revs and one hell of a noise. MUCH BETTER.
