The easy 30 minute install of the new updated "Blue Spring" will increase your fuel pressure back up to where it should be from the factory. Most 6.0's see an increase of 10 psi of fuel pressure. The added fuel pressure will help keep the injectors from out flowing the stock fuel pump, meaning no air in the injectors, and an injector that will live much longer. Most trucks will actually quiet down a little at idle, rev up a lot quicker and with the added fuel pressure, a little quicker spool up on the turbo. The kit does include all the O-Rings and hard parts to rebuild the fuel pressure housing. This kit also comes with a Brand New Billet Aluminum housing to keep the regulator spring set and to prevent leaks from the housing. This is a much thicker, stronger billet piece than the factory Cast Aluminum spring housing. The factory unit is known to leak or "weep" fuel from the sides. This kit will also help clean up the look of the factory filter housing as well., A cracked fuel filter cap can lead to air in the fuel system. That can result in hard starting or potential fuel injector issues. A cracked fuel filter cap can also cause a fuel leak, which is definitely a bad idea on a hot engine. Never worry about that again with a Sinister Diesel Fuel Filter Cap. Constructed from a single solid aluminum billet, the Sinister Diesel Fuel Filter Cap is far stronger than the OEM plastic cap. It's anodized in Sinister Blue for corrosion resistance and features a 1/8th" NPT port for testing fuel pressure.

Engine air filters are important!
Size: 8.26" x 5.63" x 2.24"
Just like me and you breathing, your car performs better when it can breathe freely and cleanly. My philosophy with an engine air filter is to replace with cheap and often. You can't control the quality of air coming into your system but you can control the filtering, so I'd rather replace the filter on an accelerated schedule with a cheap product than to invest into something more expensive and have it perform dirty for longer than it should. For my Honda CRV 2024 Hybrid, this filter fits snuggly and performs well.

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.
