Additionally, the secondary metering rods can be adjusted to accommodate changes in engine conditions, such as altitude or fuel quality.
The MaxxCarb 4K52UO is designed with durability in mind. Its brass body and stainless steel components are built to withstand the rigors of daily driving, while its hard-anodized aluminum fuel bowls resist corrosion and wear.
