same like me. I'm using diff brand as well which is better at the nozzle. The blady wd-40 nozzle is useless as the small blue thingy that you use to attach a small pipe always bust out. So now I switch to SELLEY'S RP-7.
The new packing I still saw the little blue thing in there. So, don't want to risk trying that again. Because one it drop out, the whole can is as good as nothing already.
My (cam angle sensor) CAS was set by my tuner to max..is it will cause side effect to my coil pack? because 1 of my coil pack just dead..now using M35i hks spark plug on my rb25det neo. i adjust my CAS to standard...
