Submarine snorkel kits are without a doubt the highest quality snorkel on the market today. Tested and proven, these snorkel kits are not released until they have been used and abused by Team Submarine in the worst conditions found in southern Louisiana, Mississippi, Texas, and Alabama. All snorkel kits are designed with performance in mind, meaning you will NOT loose power with a Submarine Snorkel kit. Dyno tests have proven that properly designed snorkel kits increase airflow and give you MORE POWER. Gains of 4.5hp have been realized on some models.
