how many spark plugs do my 1991 lexus ls400 need
8 beat me to it H25, man this is a freaky configuration- sorry fired too soon-
Hey Bob, it's a V8 - it has two distributors and eight spark plugs - http://www.justanswer.com/uploads/Larrycarley/2007-12- 14_191246_lexus_ignition.gif
Hey, dude...couldn't figure out how you used that elaborate formula and came up with 4....V8...very few engines have 2 plugs per...they do exist but not on a '91 Lex
that is wierd. 2 per ea. as if the explosive mixture can be "more exploded"...a bit like left-hand lugnuts.
I can remember a honda that would dial the spark up twice or was it three times just to make sure someone was home...?
you remember it. a rotor with three little contact points..yuy~
...thinkin' about the two sparkplugs per cylinder is a cheap-shot at reducing the compression by occupying just that extra amount of space...something like a raised dome piston (talk about a machinist's nightmare)-
Good evening Bob. Yes I had a Nissan pick mid 80's with z24 motor 4 cyl with 8 spark plugs. One of the best I've ever owned. My 07 dodge quad cab has the 5.7 v8 with 16 spark plugs. We will see if I end up liking it as much as the z24.
and they fire at different times from their next to ones,good idea for once
