I have TTI headers and am still trying to decide wire routing and boot angle. Not trying to duplicate original setup. I’ve looked at as many pics as can find. Looks like lots of people run them around front below headers vs running any over valve covers. I like cleaner look running under but none of the pictures I’ve found actually show boot angle that works best. Looking at universal kits that I’ll cut to length. Not sure if a mix of angles would work best or if any brands will mix. Anyone have suggestions or pics of your setup? Thanks.
