A practical fitment guide for 1200cc injectors on S2000, K20/K24 and SRT-4 builds, with clear decision rules for buying the right set.
Quick answer
For a matched set that covers S2000 F22, Civic Si K20/K24, RSX/TSX K20/K24 and SRT-4 applications, the DeatschWerks 1200cc set of four Bosch EV14 injectors is the practical starting point. Confirm your exact engine code and intake manifold before ordering, because 1200cc is a flow class, not a universal fit.
Why 1200cc is a fitment decision, not just a flow number
A 1200cc injector is large enough to support significantly more fuel than a stock injector, but the physical fit and electrical compatibility matter just as much as the flow rate. The same 1200cc set can be right for one K20/K24 build and wrong for another if the manifold, fuel rail or connector type differs. The supplied catalog lists this set as a matched set of four Bosch EV14 1200cc injectors for S2000 F22 06-09, CRZ 2011-2015, Civic Si K20/K24 02-15, and Acura RSX/TSX K20/K24 02-08. That coverage is a useful starting point, but you still need to verify your specific year, engine code and fuel system before purchase.
The SRT-4 exception: don't assume Honda fitment carries over
The supplied product record does not list the SRT-4 as a covered application for this set. That does not mean no 1200cc injector exists for the SRT-4, but it does mean you should not buy this particular set assuming it will drop into an SRT-4. Treat the SRT-4 as a separate fitment question and confirm injector length, connector type and rail compatibility with the seller before ordering. If you are building an SRT-4, the safest approach is to choose a set that explicitly lists your application rather than adapting a Honda-focused set.
Set completeness and price trade-offs
Buying a matched set of four is usually simpler than sourcing four individual injectors, because the set is intended to work together and arrives with consistent flow characteristics. The catalog price for this set is USD 341.40, with a comparison price of USD 569.00. That gap is meaningful, but price alone should not decide the purchase. A cheaper set that requires adapters or does not match your connector type can cost more in time and troubleshooting. Conversely, a more expensive set that is a direct fit may be the better value for a daily-driven car. Use the comparison price as context, not as proof of performance.
What the catalog does not tell you
The supplied product record does not include injector impedance, connector type, O-ring sizes or dead time. Those details matter for tuning and for plug-and-play installation. If you need those specifications, ask the seller or check the manufacturer documentation before buying. Do not guess based on the flow rate alone. This is especially important if your ECU expects a specific injector impedance or if you are mixing injectors with an existing tune.
Decision rules for buying 1200cc injectors
- Match the application list first: If your car is an S2000 F22 06-09, Civic Si K20/K24 02-15, or RSX/TSX K20/K24 02-08, this set is listed as compatible. If your car is an SRT-4 or any other model not listed, do not assume fitment; confirm with the seller or choose a set that explicitly lists your application. Write down your engine code and model year before you shop.
- Check injector impedance and connector type: The catalog does not state impedance or connector type for this set. Before buying, confirm that your ECU and wiring harness are compatible with the injectors in the set. If you cannot confirm, ask the seller for the missing specifications. Missing specs are a stop sign, not a green light.
- Buy a matched set when possible: A matched set of four reduces the risk of inconsistent flow between cylinders. If you only need two injectors, verify that the seller can supply a matched pair rather than mixing new and used units. Matched sets are worth the premium for tuned engines.
- Budget for tuning and supporting parts: A 1200cc injector change usually requires a tune or ECU calibration. Factor in the cost of tuning, and check whether your fuel rail, fuel pump and fuel pressure regulator can support the higher flow. The injector price is only one part of the total cost. Plan the full fuel system, not just the injectors.
Product facts
- 1200cc - S2000 F22, Civic Si K20/K24, RSX/TSX K20/K24, SRT-4: Matched set of four Bosch EV14 1200cc injectors listed for S2000 F22 06-09, CRZ 2011-2015, Civic Si K20/K24 02-15, and Acura RSX/TSX K20/K24 02-08. This set is a direct starting point for those listed applications, but you still need to confirm your exact engine code and model year.

Who this 1200cc set is for
Best for
- Honda S2000 F22 06-09 owners who need a matched set of four 1200cc injectors
- Civic Si K20/K24 02-15 and RSX/TSX K20/K24 02-08 builds that require higher flow
- Buyers who want a matched Bosch EV14 set with a clear application list
Not for
- SRT-4 owners, because the supplied catalog does not list SRT-4 fitment for this set
- Stock or lightly modified engines that do not need 1200cc flow
- Buyers who cannot confirm injector impedance or connector compatibility
