Also bro if you need a defouler i have 1 pre-drilled i can give ya for $5 shipped!
Goodluck bro and $310 better fix that dam problem![]()
Cause that's the Honda stock part # but it's really just a Denso #234-9025, same part for more than half the price I got front for $109 shipped on Amazon (worked like a charm) and my rear Denso 234-4621 on Amazon as well for $32 shipped
*EDIT* I jus noticed you're talking about the post above difference in 5, 6 &7 at the end of the stock #, either way just hope it works or that they refund if it doesn't... GL bro
