Product Descriptions:

SRS Scorpion Piston

The Stalker Scorpion piston has an extremely modular design, developed from scratch on my drawing table a long time ago. It includes all the options players could want for their SRS piston. It features a unique concept where six weights form the body itself. As the piston is made up of these weights, it is also possible to extend it with additional weights (short stroke), which reduces the cylinder volume and joule output.

Fluted Teflon Cylinder

This cylinder is a fluted Teflon version of a standard cylinder and gives your SRS A1 or A2 an aggressive look. The inner coating is applied using a cold treatment process, allowing the cylinder to retain its straight shape—something that is often not the case with heat-treated cylinders. Not only does your SRS get an aesthetic upgrade, but the special inner coating also improves energy transfer with pistons, potentially increasing joule output if your piston has a properly sized cup.

  • This cylinder is fully compatible with both Silverback SRS A1 and A2 receivers.
  • The cylinder thread works with both A1 and A2 bolt handles.
  • This cylinder is compatible with aftermarket pistons.

Rapax 3J+ RMS Spring

The Rapax Modular Spring (RMS) series is manufactured to the same high-quality standards as the Light Pull series. Built for durability and performance, these springs are designed to provide the best sniper experience. Compared to the Light Pull series, the RMS springs are considerably shorter, have a slightly heavier pull, and offer quieter shots. Additionally, RMS springs are electrically coated to prevent rust, ensuring smoother operation on the spring guide.

Good non OEM replacement filter
Size: 165465NA1C
I recently purchased the Forccord 2-Pack Engine Air Filter for my INFINITI QX50 (2025/2024-2019) and QX55 (2025/2024-2022), and overall, it’s a decent alternative to the OEM filter. Pros: Perfect Fit – Installed easily in my QX50 without any issues. Fits just like the factory filter. Good Filtration – The material seems effective in trapping dust and debris, helping keep the engine clean. Affordable 2-Pack – Great value compared to dealership prices, especially if you replace filters regularly. Improves Airflow – Noticed a slight improvement in engine responsiveness and fuel efficiency. Cons: Not OEM Quality – The filter material feels a bit thinner and less sturdy compared to the original Infiniti filter. May Not Last as Long – While it works fine now, I’m unsure if it will hold up for the same mileage as an OEM filter. No Installation Instructions – Though easy to install, a simple guide would have been helpful for first-time users. Final Thoughts This Forccord air filter is a good budget-friendly replacement that fits well and performs decently. However, if you prioritize OEM durability and quality, you may want to stick with the original Infiniti filter.

Verify your engine size! 17220-5AA-A00 filter for 1.5 liter turbo. 2.0 uses different filter.
Size: 17220-5AA-A00
17220-5AA-A00 for the 1.5 turbo engine (we have a 2017 Civic EX-T), 2 pack of filters, use 1 at a time so 2 intervals, about 15k-30k miles per interval, it's about 30k-60k miles worth of air filter. Works as it should, fits, compatible, nothing fancy, does its job. For the turbo it's a few screws or nuts (use the socket, less chance of stripping, don't over tighten when you put the cover back on), front of engine compartment, you could do this while dressed in fancy clothing. First mechanical thing that I had our son do, I gave him guidance, literally the first time he popped the hood. Took maybe 10 minutes, and that was him being careful and being new to using tools. I'm not a professional but I work on our vehicles, have done a bit more than basic maintenance. This air filter replacement procedure is as straightforward as they get.

Filter fit perfectly.
Size: 17220-5LA-A00
It fit, so that was my first concern in buying this as the price was low for a 2-pk. I bought it since it said good for 24,000 miles whereas another I was considering was only 12,000. I know I went more than twice that so will see how it holds up. Coming from a brand I never heard of, but what was available on Amazon.
