Impeccable Workmanship!!

This is the first time that I have purchased pistons from Combustion Technologies. Ordering was easy! I asked for a matched set and they sent me exactly what I asked for. I have bought pistons for OEM and another major engine parts suppliers but, I will not buy from them again. The quality of the product supplied by Combustion Technologies is unmatched in my view. I just wished that they made other engine parts as well. Thank you for these quality pistons!

Great Pistons

Great Pistons SkyMan on Apr 17, 2020 I have installed over 8 of these pistons on my Lyco IO-360 a1b Never a problem or a failure. They are easier to install new than to try and clean out the grooves from the old ones.
