BUZZARDCATCHER ( 5" BUTTERFLIES ) Butterfly Blanks for EFI Conversion- Block offs-
Need 2 FOR ANY GAS ENGINE - BUZZARDS NEED TWO OF THESE FOR EFI UNLESS ALL OUT ALCOHOL RACING
Helps prevent butterflies being sucked shut when running a Blower
To help with street driving we recommend blanking off 2 of the outer butterflies. This reduces the amount of air the can flow past the butterfly and tames your engines down so its not too snappy.
These blank plates are simply Tack Welded into the injector and fully sealed with a fuel resistant sealer.
