Spark plugs...

[mikester328]

What's the reason I would change spark plugs in my 318? they have no effect on performance right? I heard that by using 93 grade gascan help preserve the spark plugs a little longer... is this true? thanks...

btw, I wasn't sure if posting this topic here was the right place but since I have an E36 I thought I'd post here

spark plugs make explosions.

If you made an average of 800 explosions a minute you were awke, you'd wear out.

Same with plugs. As they age, they become worn. If the engine is in bad condition, then the spark plugs could be dirty, grimey, oily, melted, and a wide range of other things. Changing them can tell you a lot about the cars condition. Plugs also have a minimal imnpact on performance. Mine were changed today, and the car was noticeably more responsive.

If you haven't I would change them just to take a look. Normally 20K intervals are about right, but due to the ease of this particular task, I would just chage when neccessary. Carbon build up is quite noticeable as is any other foul.

DEFFINATELY replace with oem IMO, for more info check my review...{LINK}
