Features

  • Experience an Obvious Difference: Whether you are noticing a delay in acceleration, less than average gas mileage or own a higher mileage vehicle, our Max Thrust engine air filters will provide a clear and cost effective upgrade over stock performance
  • Trap 2X Dirt vs. Standard Air Filters: Our unique Hex-D pleat design creates maximum holding capacity for trapping unwanted dirt and debris without compromising airflow like standard air filters thanks to multiple layers of progressively finer filter media that allows air to flow freely even when the filter is dirty
  • Increased Power and Mileage up to 15K Miles: Deficient airflow can cause your engine to work twice as hard to suck in the minimum amount of air it needs to perform regularly, resulting in poorer gas mileage and lower power efficiency; Max Thrust air filters are designed to give your engine a break by delivering as much clean air as it needs to perform optimally up to 15K miles

  • Great Filters! Some car models require you to gently squeeze filter sides as you inch it in.
Size: MT-290 1-Pack
Spearhead engine air filters are awesome and so are the cabin filters. Been using them for years. I have an 18 Accord, 19 Odyssey, and a 21 Passport. The cabin filters slide right in for the Accord and Passport. It's a tight fit for the Odyssey but you can inch it in by squeezing the sides of the filter as you push. Pulling out will be a bit rough a year later since it's pretty much squeezed. Note, the accord is a different size filter from the Odyssey and Passport which are the same. Never had size issues for the engine filters. I replace the engine filters annually after pollen season but can go longer. ... show more

I started out with whatever came from Toyota dealership from the last oil change they gave me while under warranty, I assumed they changed the engine filter with it. Since my last oil change, I didn't change my filter, because in my area I can still go beyond the recommended change due. Been a few months since my last oil changed, and last 2 rounds without engine filter change. Keep in mind though this was unique to my area. After inspecting that Fram looking filter, it was a little dusty on one half but the other half dirty, but still not too bad, but best to change at this point anyhow. This new Spearhead MPG Defense Max Thrust Engine filter was easy to install, and the metal grate material over the accordion-like filter paper, I'm assuming may be an added benefit like for static energy to trap trap more from getting into the engine. I didn't realise this one was for high mileage vehicles, but I think it a bonus for something with a little well over 50K miles on it. My only disappointment is that they care only enough about us to make it overseas in China/CCP than local to help out our own economy and livelihoods better says a lot. So, the rating is 3.5 stars but rounded to 4 for at least assumed workmanship. ... show more
