FAQ

Common Questions

Should I replace all nozzles at once or just the bad one?

Always replace all nozzles as a complete set. Mixing old and new nozzles causes uneven fuel delivery, rough running, and poor performance.

How many nozzles do I need for my engine?

CAT 3054 and 3056 engines use 4 nozzles (4-cylinder). Order quantity 4 for a complete set. Price shown is per nozzle.

Is this an original CAT part or aftermarket?

This is an OEM-quality aftermarket nozzle manufactured to CAT specifications. Same performance as genuine CAT parts at a better price.
