    • happy engine. good mileage

Fit my 05 Tacoma great! Have had good response with the engine and it's acceleration. Fuel mileage is back on par. Will buy again!

    • Sturdy and well built, not bad for the price.
Size: CA11476
This engine air filter had a premium feel, and look to it. Fit just like OEM, and I like that it's rated for 15k mile life, although I change out air filters every year. I like that it has good ratings and the price is on point. It's my 1st time using this brand of air filter and I did clean the throttle body so we'll see how it performs in a year of use. If I see it's not so good at filtering contaminants I will for sure write another review. ... show more

    • Had a few sensor warnings initially, but seems to be fine now
Size: Premium Engine Air Filter
Now this could be me, but I had a few MAF sensor warnings after I installed this filter. I wiggled it a few times to make sure it seals properly to get rid of the warnings but it happened a few more times. Knock on wood I haven't been getting them for months now, as it may have sealed itself into position over time. The installation is not very easy due to the car's design, so that of course contributes to the issue. ... show more

    • Durable air filter
Size: Advanced air filter
Great reviews so I purchased this for my 21 Acura TLX. This was the first time I changed the filter on my car. Very durable and thick, so far so good. It was super easy to install, don’t see much of a change in fuel usage but that wasn’t a concern. Great value for money will buy again.

    • Stands the test of time!
Size: CA10159 Air Filter
I've bought this twice & its a great filter that stands the test of time... I have a 2007 prius (base model, for reference). I lagged on changing the filter for some time & had my boyfriend install the new one yesterday. Very happy with the filter, it's affordable & even if you use one for a whiiile (I'm talkin 2 years) before replacing it... it isn't gunked up like all the other flimsy ones I've had in the past!! I don't suffer with bad, year-round allergies when driving with this 1 installed. I know the quality I'm getting when I reorder & use this filter. I'd recommend this to my friends :) ... show more
