Will not fit 98 Honda Accord

Website said that this product was an "Exact Fit" for my 1998 Honda Accord EX 3.0L V6; however, the wire was not long enough. Just wanted to let anyone else looking know.

                    just use a 7/8" open wrench or use a oxygen sensor socket and ratchet. Might need some wd-40 to loosen a bit and a breaker bar.

                      I had to replace the exhaust, from the flex pipe all the way back, on my 02 Honda Accord w/ a 4 cyl engine. I was on the fence of whether or not to replace the O2 sensor downstream which goes in the CAT. Although with replacing all those parts I decide it was best to replace the O2 sensor as well. It fit perfect and was very easy to install there were no adaptations needed to make it work.
