Description

Put an end to mysterious air/fuel ratios, jet changes, and cold-start rough idle troubles with Holley Sniper EFI. Affordable aftermarket fuel injection is here and it couldn't be any easier to install on your vehicle. Holley Sniper EFI is a perfect match for any muscle car, classic truck, street rod, or nearly any other carbureted vehicle. Economically priced to save your hard earned money for other parts of your build; Holley Sniper EFI is a self- tuning, plug and play fuel injection system that takes all the trouble and guesswork out of your switch to modern electronic fuel injection. With over 100 years of building quality fuel systems, you can trust Holley Sniper with all your electronic fuel injection needs! Holley Sniper EFI is packed with all the features that your car or truck needs. This throttle body fuel injection replaces any square bore or spread bore style 4-barrel carburetor. The built in ECU keeps the wiring neat and tidy with no need to run the computer and associated wiring back into the cab of the vehicle. Connect the 4 necessary wires and you're good to go. The self-learning ECU takes care of setting the baseline tune while the full touchscreen display allows you to fine tune as you please. Sniper EFI throttle bodies utilize OEM style TPS and IAC modules for dependable and serviceable use. Life is too short to hassle with cold start issues, hesitations, flooding, and carburetor inconsistencies. Leave that old 4-barrel to rest and bring in a new era of performance, reliability, and fun with a Holley Sniper EFI system! Holley Sniper EFI Master Kits include everything you will need to get your new Sniper EFI throttle body setup and running on any of your vehicles. Master Kits include 20 feet of 3/8" EFI fuel hose, in-line electric fuel pump, pre and post filters, return bulkhead, and all of the needed fuel fittings and hardware to get your system plumbed, wired up and running in no time.

  • Great product
Great product just what I needed

  • Wow
Really performs nicely on my 351c (2v heads). Smooth and responsive, especially at low speed in traffic. Fuel pump is very loud. I may go to an in the tank set up to remove the noise there

  • Runs great
Huge improvement over carburetor. Would give this 5 stars all day but the fuel pump is annoyingly loud. Will likely be making a change in that area.

  • Bad customer service and problems with item.
I ordered the master kit. Took more than thirty days to finally almost finish build. The pump cracked when my mechanic attempted to attach fuel lines. Plastics PUMP. Holley sent me a better pump with no problems. Finally tried to start her up and the screen came up as no O2 censor connected. My mechanic contacted Holley. tried another O2 Censor and determined the problem was the ECU in the carb itself. Contacted Amazon and was told since it was past the 30 days, kit was not their problem. Had to return it to Holley after spending close to 100.00 dollars via UPS and was told by Holley it would take 4 weeks minimum to hear back from them. They will graciously pay for return shipping. You decide. ... show more

  • Runs like a champ
Took some time to install but it was well worth it effort

  • Solid and simple
This unit is a beast. Complete woke up my old 350 sbc. Was not the hardest thing to install but you will need to set aside some time to make it all look super clean. The kit is exactly what it says “ complete “.
