when should i have my spark plugs changed?
how important is to change it? what brand do ppls recommend?

thx alot

 

depends on your mileage. its important when they get worn out. consult owners manual for the interval. I would use the OEM plugs from honda.

 

Interval is every 105,000 miles.

 

leave the plugs in for 100Kmiles? hope this is all average driving.

what if over that extended period some plugs deside to crack, giving you extra shrapnel rolling around in the engine.

pulugs are super easy to change and are not that expensive.
