The newly developed ESX QUANTUM QE series is a class of its own. Conventional high power digital amplifiers usually cause interferences in the vehicle and disturb the radio reception. Not so with the new QE models: During the development period, special attention was paid to achieve an emission-free music playback. Also the sound is perfect,  because high-quality components guarantee an audiophile sound experience at its best. The features are also impressive: Auto Turn-On Function, EPS, variable crossover filters – everything your heart desires is on board. High-quality connectors and screwed RCA sockets complete the perfect appearance. All amplifiers are delivered with a sophisticated level remote control, which can be installed very space-saving with or without housing.

CORRECT FIT as Advertised...
IMpressed with this product. IT DEfinitely fits my 2023 Honda Pilot, EX-L with the 3.6L engine. There are several engine filters adverised on Amazon that "Say" they fit a 2023 Honda Pilot ONLY come to find OUT that most do not!! It appears that in 2023, there were some changes made to the engine air flow system that modified the layout somewhat. So my advise is to do YOUR homework and reseaech it to some degree so you're NOT having to send the filter back and REorder another one. My recommendation is to find the Honda or say, Fram part number 1st, then put that # into the Amazon search bar to ENsure you're ordering the correct one. BUT againt this one DID fit my Honda Pilot as advertised!!

It’s ok for a short period of time.
Meh….the filter is glued at each end versus clamped into the housing like the OEM filter. Will probably get a different brand or OEM in the near future.
