If cars like yours typically suffer issues such as backfiring and stalling when using a fixed-ratio atmosphere-venting BOV, the Respons can help. By adjusting the venting bias to suit the car you can achieve a blow-off sound without having to put up with the issues. Like all GFB valves, the Respons utilises GFB's proven TMS Technology to ensure rapid boost recovery on gearshift and optimum throttle response, as well as the ability to withstand boost pressures of 100psi+. Put simply, it can hold more boost than any turbo could produce.

  • Patented Venting Bias Adjustment

Convenient and Cost-Effective Air Filter Set for Gasoline Engine
Size: CRV (2023-2025) 1.5L Gas, Size: CRV (2023-2025) 1.5L Gas
Why did you pick this product vs others?: The set includes both the engine air filter and the cabin air filter, which I find extremely convenient because both usually need replacing around the same time—especially if you drive in dusty environments or have seasonal allergies. Ease of installation: I replaced both filters myself in under 20 minutes using just basic tools. No instructions are included, but a quick search online brought up several helpful videos tailored to my car model. Both filters fit perfectly without any force or trimming needed, which isn’t always the case with aftermarket brands. Functionality: From past experience, replacing the engine air filter regularly (every 12,000 to 15,000 miles as suggested in the owner’s manual) helps maintain better fuel efficiency and extends engine life by keeping debris out of the combustion chamber. After swapping in the new filter, I noticed the engine ran slightly smoother—especially on acceleration. Smell: The cabin air filter is equally important, particularly for passengers with allergies or sensitivity to airborne particles. I could immediately tell the airflow from the vents was stronger and fresher-smelling after the replacement, which suggests the old filter was overdue. Value for money: The ITESIER Cabin and Engine Air Filter combo pack is a smart buy for anyone maintaining a gasoline-powered vehicle like my Honda Civic. This combo pack offers good value for money compared to buying each filter separately. Quality: Overall, if you’re comfortable with basic DIY car maintenance, this kit is a great choice. It’s affordable, fits properly, and provides an easy way to knock out two important maintenance tasks in one go. Filter quality: The filters are high quality. They work without problems. Just be aware that this is designed only for gasoline engines—it won’t be compatible with diesel or hybrid powertrains.

Exactly what I needed
Size: CRV (2023-2025) 1.5L Gas
I'm not sure how much there is to say about an automotive cabin air filter. I double-checked the specs to make sure this was compatible with my car, ordered the filter, then installed it. It fit, it didn't have a weird smell, I haven't thought about it since. That's exactly what I want in an air filter. Five stars!

A perfect fit.
Size: 26" 26" 13"
It's not often you get to say 'perfect' about almost anything, but this is one of them. The product was a terrific price, it came in a day, was packaged perfectly, was easily removed from clever packaging, it was simple and obvious how to install, and it fir perfectly, both front and back. True OEM fit, feel, and finish. Like I sad, peeerfect for my VW Touareg. As advertised. 5-star. And I ask again, how many 5-star ratings have you given? This is my first and I'm n old guy. Been doing business on Amazon for decades.

Fantastic blades at a great price.
Size: 22"/20"/14"
Perfect fit and work better than the expensive brands, like rain x. Have had no streaking issues as I have had with many inter brands. Great price for the 3 pieces as well, and highly recommend.

easy install, cleans well
Size: 26" 20" 12"
took less than 10 minutes for front and back replacement: a lot of that was spent on figuring out how to get rear wiper removed. perfect fit. by geometry, installing passenger front wiper was a little more tricky simply because of the reach issue [and I have long arms]. but that's not a problem with the wipers. windows were covered with pollen. using the spray and wipe option, they cleared up beautifully in one pass. note: OEM has a heavier bow with a joint in it to adapt to window curve. this wiper has a lighter, more flexible bow with no joints, but hugged the window perfectly. it may help that it's almost 90 F outside. waiting to see how it does in colder weather and with snow, and to see durability.
