BACKFIREDual Universal Automotive Flame Exhaust Thrower Fire Complete Car,Motorcycle,Truck Throwing Kit

Junk don’t buy, only a glorified relay inside a box, and the wiring isn’t up to completely correct, never got mine working because from my experience these type coils require the use of capacitors and resistors, or else you’ll fry the coils most likely, I will report to Amazon, this should not be considered a complete ready to install and make flames if it’s really not!

Everything is set up and I'm getting volts to the coil packs but the coil packs don't even work changed spark plugs and they still won't switch on the spark plugs.

good for beginners ...will not work on modern engine , or engines with multi spark and stand alone systems. not impressed. the system I used on the 49 in the picture was cheaper and more reliable.

Was never able to get them working I put the on a 74 Chevy running straight pipes and followed directions perfectly button starts to kill truck when pushed but no spark I think the controller box never worked so it was a waste of money I asked for help but never got a reply

thank you so much

Pretty much a rip off of get the controller for 30 bucks and save 145 And by your own coils and spark plugs simple To build your own

Junk, burned out the points on the 283. Tore that junk off and sent it back.
