Code: N/A


In Stock


If you are looking for the most efficient, purpose built, dry nitrous plate, this is it! 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 and built for racers that need a dry plate with a true 450 HP rating. This is the only dry plate on the market that comes flowed with actual pounds per hour numbers for nitrous flow.

The I-S Billet DryFI nitrous plate system is designed with great looks and strong performance in mind. 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.

The Plate

The plate is ½” thick billet aluminum anodized black and laser engraved with the Induction Solutions logo. The holes are precision CNC machined and have the correct area to support the max horsepower rating. This one piece construction means no tubes to index or bend and no epoxy or O-rings to fail and cause a leak.

The Solenoids

This plate system comes with our SuperMax Bottom Exit Nitrous Solenoid. The solenoid comes with a filtered inlet fitting installed and mounted on one of our billet aluminum solenoid brackets. The nitrous solenoid has a high amp draw coil and a .125 orifice for improved flow. This is the same nitrous solenoid that is used on our X275 Direct Port Systems. Each Billet DryFI Plate Kit is flowed and comes with custom jet mapping and brass widebody jets for 50-450+ HP

The Look

This plate is “blacked out” it has braided stainless solenoid lines covered in black sleeve. Along with black output fittings from the solenoid. There is a chrome solenoid cover option as well.

The Induction Solutions Difference

There are many companies providing nitrous products to the market, however none offer the same tech support and quality of kits that we do at Induction Solutions. All of our systems are completely blueprinted with attention to detail and hand built to order. Each plate system is flowed for every tune up from top to bottom in 50hp increments and we provide a hand written tech sheet specific to every system, not some mass produced, one size fits all, print out. All of our AN lines come standard with a protective sleeving that acts as a conductive insulator and makes the line far less abrasive to painted and anodized surfaces than industry standard uncoated braided stainless lines. If you decide to purchase one of our complete kits, you will receive a truly complete kit that includes details like a purge kit and a race ready bottle including a gauge, NHRA racer safety, and bottle nut. All of the aforementioned parts are things most companies leave out and want to sell you separately, even though they are necessary to run the system properly and safely!

This complete kit includes: billet plate, solenoid, filtered inlet fitting and hose all assembled on a billet solenoid bracket. A 10lb OR 15lb bottle with a -6 bottle nut, racer safety, and 1 1/2″ liquid filled nitrous gauge installed. Mounting brackets for the bottle, a -6 supply line, -6 purge kit, as well as, all the electrical hardware. The complete kit also includes custom I-S blue print, flowing, stainless jets, jet mapping and the great tech support I-S is known for.
