Product Description
Honda K-Series Fuel Rail Spacers for Bosch-Style Injectors
The JBtuned K-Series Fuel Rail Spacers provide the additional spacing needed between a compatible aftermarket fuel rail and the intake manifold when using Bosch-style fuel injectors on Honda K-Series engines.
Instead of stacking loose washers underneath the fuel rail mounts to achieve the required injector height, these spacers provide a solid and consistent mounting surface that keeps the fuel rail properly supported.
They are a simple solution for K20 and K24 fuel-system combinations where the injector and fuel-rail setup requires additional rail-to-manifold spacing.
Designed for K20 & K24 Fuel Systems
Designed for compatible Honda and Acura K-Series K20 and K24 applications using an aftermarket fuel rail and Bosch-style injectors.
Common applications include modified K-Series engines, K-swaps, upgraded fuel systems, and other combinations where injector height requires the fuel rail to sit farther away from the intake manifold.
Fuel rail, intake manifold, and injector combinations vary, so verify that your setup requires additional rail spacing before ordering.
Proper Fuel Rail Spacing for Bosch-Style Injectors
Different fuel injectors can require a different installed position than the injectors originally used with a particular K-Series fuel rail and intake manifold combination.
These spacers sit between the aftermarket fuel rail mounting points and the intake manifold, moving the rail outward to provide the additional clearance needed for compatible Bosch-style injectors.
The goal is to maintain proper injector positioning while keeping the fuel rail securely supported.
No More Stacking Washers
A common way to create additional fuel-rail clearance is to stack individual washers underneath the rail mounts.
The JBtuned spacer replaces that improvised washer stack with a purpose-built spacer that provides a stable, repeatable stand-off between the fuel rail and intake manifold.
This gives the fuel rail a cleaner mounting arrangement and helps keep the setup solid once everything is properly tightened.
Rigid ABS Construction
The JBtuned K-Series Fuel Rail Spacers are made from rigid ABS plastic.
The spacer design provides a solid mounting surface between the intake manifold and fuel rail without requiring multiple loose washers at each mounting point.
Compatible Applications
These spacers are intended for compatible combinations using:
- Honda / Acura K-Series engines
- K20 engine combinations
- K24 engine combinations
- Compatible aftermarket fuel rails
- Bosch-style fuel injectors requiring additional rail spacing
Because aftermarket fuel rails, intake manifolds, and injector dimensions vary, these spacers should not be assumed to fit every possible K-Series fuel-system combination.
If you are unsure whether your setup requires these spacers, contact JBtuned before ordering.
Not an OEM Replacement Fuel Rail Spacer
These are not intended as replacement factory Honda fuel-rail insulators or OEM fuel-rail mounting spacers.
The JBtuned spacers are designed specifically to provide additional spacing for compatible aftermarket fuel rail and Bosch-style injector combinations.
What Comes With the Kit
- 2 JBtuned K-Series fuel rail spacers
Fuel rail, injectors, intake manifold, and mounting hardware are not included unless otherwise stated.
Installation Notes
The spacers install between the compatible aftermarket fuel rail mounting points and the intake manifold.
Before operating the engine, make sure the fuel rail is securely mounted and verify that each injector is properly seated and sealed at both the fuel rail and intake manifold.
After installation, pressurize the fuel system and carefully inspect all injector and fuel-rail connections for leaks before starting or operating the vehicle.
