DDP High Flow Injectors

98.5-02 Dodge 5.9L *150 hp

These 150hp injectors will produce approximately 500+ hp.

We do not recommend using injectors of 110 or above on a stock truck. A performance turbo and other supporting products are recommended to support these injectors. With a box and turbo, 110 hp injectors are capable of 450 horsepower. DDP's 150 hp injectors are capable of 500+ hp with supporting products and our 200 hp injectors are capable of 600+ hp if paired with the right turbo. Please contact us if you need help in deciding what turbo to purchase in order to receive maximum performance out of your injectors.

Your mileage will increase over stock with these injectors. You will likely see 1-2 miles per gallon, depending on how you drive.

Included with these injectors is a set of copper washers and a core form. Please fill out the core form and return it to DDP with your cores. See our policies page and DDP’s policies if you have questions about core returns.

Please note that some 98.5 trucks will need connector tubes. If your engine serial number is less than 56462598, you will be required to purchase them or your new injectors will not seal properly.

As always, this product is covered by DDP's 3 year unlimited mileage warranty and a 30 day money back guarantee.


This product requires purchase of the core charge titled "DDP CORE CHARGE $150 VALUE." This charge will be refunded IF we receive your core injectors within 30 days. See our policies page for details.
