Our 602 intake matched spacer creates more power and on-track feel than anything we've tested it against. The main reason we are able to achieve this is by, you guessed it, intake matching. 

For this spacer in particular we have kept the 4 hole aspect to increase air peed as much as possible, then tapered the inside pf the spacer to the outside dimensions of the intake, allowing for air to have a smooth transition, decreasing your chance of creating turbulent air. Turbulent air = less power. 

Our 602 spacer is also tapered, not side to side like most, but front to back. This is to compensate for the forward angle of the 602 intake. By putting our spacer on, this levels the carburetor out and keeps any potential fuel problems at bay. 

!!DISCLAIMER!!: As the intake manifolds for 602's are a cast piece, fitment may vary due to casting flaws.
