Fuel Injector Service kit for Honda fuel injectors (Accord, Civic, CRX, Prelude, etc.). This kit contains the less common thicker style lower seal ring (oem p/n 16472-P10-A01). Please look closely at the pictures to determine if your injectors utilize this thicker style lower seal ring (7mm thick). The thicker style seal ring is found on older Hondas from the mid late 1980’s and many OBD1 vehicles up to 1995 including Accord 1985 thru 1989 - Civic 1986 thru 1995 - CRX 1985 thru 1991 – Del Sol 1993 thru 1995 – Prelude 1993 thru 1995. Kit contains 12 O-rings, 4 Upper Grommets, 5 Pintle caps (4 shown in picture but 5 included) , 4 Lower Seal Rings (lower grommets) and 5 Micro basket Filters (4 filters are shown in picture but kit contains 5 in case you have a mishap). 12 O-rings are included because Honda injectors used different size/material upper O-rings throughout the years. Therefore, all three common type/size of upper o’rings are included. Clogged micro basket filters are a source of fuel injector malfunction. Free shipping within the USA. Worldwide shipping cost is $11.00. Paypal accepted.
