XDI 2500cc High Flow Injectors | 17-23+ Type R FK8 & FL5, 23+ Integra Type S DE5

Fits:

• 2017 - 2021 Honda Civic Type R FK8
• 2023+ Honda Civic Type R FL5
• 2023+ Acura Integra Type S DE5

E85 recommended — not stable on pump gas due to injector size. Perfect cold start and idle should not be expected at this flow rate. An HPFP60 is recommended to fully utilize injector capacity. Requires custom tuning, not plug and play. Compatible with Hondata FlashPro, MoTeC, standalone ECUs, and WinOLS.

_______

These are for a genuinely built engine on E85, not a mild street upgrade. XDI's 2500cc injectors deliver 110% more flow than OEM — 2500cc/min at 100 bar, scaling to 3500cc/min at 200 bar — while keeping a 100% drop-in fitment with an optimized spray pattern. At this size, you're trading some idle refinement for serious top-end fuel capacity, which is exactly why E85 and an HPFP60 are the right pairing to actually use what these injectors offer.

Every set is individually tested and matched at three critical operating points — idle stability, static flow reference, and WOT performance — with full documentation provided so your tuner has real data instead of guesswork.
