The TR55 is NGK-3951. Keep in mind that these are gapped to .055. Some prefer the .040 gap, which are TR5 (NGK-2238). I just picked up a set of 2238 from Maryland Speed a few weeks ago.

thank you!! I just picked up the TR55 and cheap too. $1.49 each

Was expecting to pay the usual $5.99

thanks again.
