I can also make some extra long for you HEMI guys, and 2JZ sets of 6. Multiple color options for no heat safety plugs, and limited color options for high temp plus made with ABS. Keeps engine from getting debris in it. If you need high temp

Great quality
These o-rings worked perfectly on a 2010 Honda Odyssey. Stopped all the leaking from the pump. Highly recommended

GARBAGE. Don’t waste your money
Absolute trash. The low pressure o-ring (orange) broke and split and broke in half after less than two hours of installation. Don’t waste your time and money on these cheap Chinese o-rings. The OEM Honda o-rings are literally cheaper and light years ahead of these in quality
