Hey guys, I recently picked up an 01 F4i. It looks like it's in very good shape aside from some scrapes in the lower fairings, and only has 15k miles. But it had barely been ridden in the past year and something was wrong with the fuel system. I just got the fuel injectors back from getting cleaned so I went to the bike shop to get an oil filter and spark plugs. (2 of them were fouled bad) The parts guy looks up the plug, and the NGK model listed costs $30 each. I also bought plugs for my GSXR and those NGKs were only $6! I asked if there were any alternatives. There was 1, but at $16 each that's still a lot. I'm trying to get this bike running good again for as little money as possible. Are there any reasonably priced alternatives? Am I stuck shelling out for overpriced spark plugs? Should I try to just clean them? Your suggestions are appreciated.

 

my bike has 14000 miles on it and i just changed the plugs also. i figured it was worth it to spend 20 bucks for each plug from the honda dealer.

 

Yea, I had a feeling I'd hear answers like that. Not what I wanted to hear though.

 

www.sparkplugs.com ... trust me, you will NOT find them cheaper, unless of course you find some on ebay. I've gone through a few sets of plugs in my bike after 88k miles, so I've looked around everywhere. Haven't found anybody beat them @ $11/plug for mine. Now don't forget since you have an '01, yours takes a different plug than the '02-06 F4i's. I don't know if you have a service manual or not, but just to make sure you got the right part #'s when looking stuff up, yours are:
