Faster response time improves wideband feedback control, and can provide a safer, more powerful and accurate tune. AEM's Wideband Controllers with X-Digital technology can reduce deadtime and improve the performance of your vehicle through more accurate AFR tuning. Deadtime is the delay between when exhaust gas composition changes and when that change is reported by the O2 sensor. While flow of exhaust gases can affect deadtime, it is not the only source. Often, the sensing element’s response to the gas is the largest contributor to deadtime.When tuning an engine using wideband AFR feedback control, deadtime affects the data you are looking at because it is reported in a different operating location than when it occurred. This means whatever changes you make to the base fueling will likely be in the wrong timeframe. This can be particularly dangerous to high cylinder pressure applications, and EFI systems that use feedback control.

Good value, fit 2023 CRV 1.5L
These filters arrived wrapped in plastic in a cardboard box, shipped in a standard Amazon box. Initial quality seems very good. I've previously used store brand filters and oem filters in our 2023 CRV 1.5L, and these look comparable. They fit fine. If you have not changed your filters, there are good youtube videos that show how to do it, the CRV is well supported and pretty straightforward without having to buy a bunch of special tools. If you don't want to spend $100 at the dealership, these are a good value and only take about 5-10 minutes total to change once you have done it a few times. First time out, give yourself 30 minutes and be patient!

Fits Perfectly. Can't beat the price. Don't Hesitate....
Actually this filter combo fits my customers car perfect. Some after market filters you have to finagle a little to make them fit, however this engine air filter and cabin filter fit perfect...Great deal for both filters.
