This is a cylinder block with a 90° angle for the oil temp sensor, so it will be plug and play ready to be installed on the fuel injected CRF110F.
Uses a straight mount for the oil temp sensor and does not use the sensor cover because of that.
If you install this specific cylinder block on your CRF110F that you will need to install also the KWB cylinder head type.
If you install this cylinder on a carbureted bike, then you need to close the hole for the oil temperature sensor with a bolt and a copper washer.

Note:
Case boring required: If you don’t have any experience working on your engine, we highly recommend having a professional technician install this kit or, at a minimum, purchasing the shop manual for your bike available from your local Honda dealer. Case boring requires precision and it creates a ton of metal shavings. Its best to completely disassemble the engine when you bore a set of cases. That way you can ensure the cases are 100% clean for reassembly.

IMPRESSED!
Item Package Quantity: 1, Item Package Quantity: 1
I bought this for my Honda civic 2017 lx 1.5 and it is a perfect fit. I didn’t realize how important it is to change it. Let me tell you if you are thinking about buying this, it’s your sign not JUST because of health which is vital and first and foremost but the PRICE! At any oil change or auto shop they will charge no less than 50$ and I’ve seen higher. I will continue to buy this brand. I will update in my next 5,000 miles. 8.00$ or 50$+ and the quality is EXACTLY the same, your choice.

2016 Honda civic ex

Fits perfectly in my 2016 Honda Civic EX. Installation was quick and easy, and the air coming from the vents smells much cleaner now. It seems to trap dust and pollen well and is a good replacement for the OEM filter.

Perfect fit and reasonable price. Easy to replace in my 2019 Honda CR-V. It takes about 10 minutes to replace. Don't let a dealership rip you off.
