will the spark plugs off a 95 accord ex fit a 90 crx s1? just wondering because i have an extra set in my toolbox

 

one more thing to add.. what viscosity oil do you guys use ( for tranny and engine).. i live on the eastcoast and the temp varies with season(durr) .. i was gonna use 5w30 syntec blend just because i have a case of it lying around too. .. i know these are duh questions but i just got this crx and i m just doing routine maintenance before i start driving it daily

 

I don't know for sure if the plugs will swap, but you can look and find out. Pull a plug from your crx and hold it up to the accord plug--make sure the thread length is the same! Then check the heat range (i believe 7). Then regap if necessary. You can go on the NGK website and get a breakdown of the number/letter code also. As far as the oil--5w-30 should be perfect and syn blend would be a good upgrade to conventional oil.

 

I don't think they will.... the Accord uses zfr5f11 and your crx uses rc9ycn4.
