Spark Plug Holder for Reading, Indexing, or Setting PlugsI had someone reach out to me about a spark plug holder for setting reading plugs, so I designed 2 different styles. Plugs can be inserted in either direction. Both can be customized with your firing order, name, and engine style. Will be 3D printed in PETG for oil fuel resistance and is available it multiple colors. Large is 3 rows of 8 plugs, Small holds 8 plugs in the correct cylinder layout.

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.
