Frequently Asked Questions About the RSX 02-09 ID1050-XDS Injectors
How do I know if I need the 14mm RSX injector kit or a smaller option?
The 14mm kit is the most common choice for RSX 02-09 models with aftermarket top-feed fuel rails, like Radium or Tomei. Smaller kits are only needed for specialized or less common fuel rails. Always confirm your rail specifications before ordering.
Will the 1050cc RSX injectors cause idle problems on a 4-cylinder engine?
No, the ID1050-XDS injectors feature precise dynamic matching and detailed dead-time data, ensuring a smooth, stable idle and excellent low-throttle drivability even on E85 or performance fuel blends.
Are these injectors suitable for a 200-220whp naturally aspirated RSX build?
Yes, these injectors comfortably support that power range, maintaining consistent fuel delivery without running at high duty cycles or risking lean conditions.
What benefits do the XDS injectors provide for track or spirited RSX driving?
The XDS series has stainless-steel internals that resist corrosion and are fully compatible with E85. They also come with plug-and-play wiring, ensuring reliable installation and performance during aggressive driving.
Will these 14mm injectors fit under the stock RSX intake manifold?
Yes, the 60mm ID1050-XDS injectors are designed to fit compatible top-feed fuel rails under the stock intake manifold without clearance issues, making installation straightforward.
