Spark plug removal
 

How do you remove the coil packs , the ones that or on each individual plug, have undone the 10 mm bolt so do you just tug it off(ooer) or is there a correct way. Checking spark plugs for condition and gap ,0.7 is that correct?
95 WRX ,exhaust and panel filter,dumpvalve are the only mods running it on O.max // NF.

Hold the bolt & pull firmally whilst giving a little wiggle, (Not your @rse either)
or grip the coil pack firmly & do the same , teasing your fingers behind. Don't wiggle to much though v small amount.
