VERY LIMITED SUPPLY ON THESE KITS.
Here is a 4150 SV-Xtreme Nitrous Plate System! This system was designed with single venturi Carburetors in mind. It is race bred and makes great power, great for streetcars and ET class racers. This is NOT a cheapened up kit, it’s built with all the quality workmanship and parts you have come to expect from I-S. It’s designed around and built for racers that need a plate with a true 400 HP rating. What makes our plate systems a step above an average out-of-the-box plate system is the way we blueprint, assemble, and jet map the system as well as the great tech support we provide.
