yewman Posted September 25, 2005 Share Posted September 25, 2005 I have a 1999 legacy with EJ20E 2 litre engine. In one part of the operators handbook it quotes BKR6E plugs for cars with CAT, and RC10YC4 without CAT.In another part of the manual it says the opposite. Which is right ? Also it gives the gap 39-43 thou inch with CAT and 28-31 thou without. Is this correct? My car has a CAT & the previous owner had them set at 31 thou Regards Yewman.....

Setright Posted September 25, 2005 Share Posted September 25, 2005 Well, BKR6E are NGK plugs and the others are Champion. Most people here will agree with me: Use the NGK! "V Groove" perferably. BKR6E-11 or perhaps BKR5E-11 The "5" plugs are a bit hotter tipped, which is good for self cleaning if you run a lot of low rev and shorter trips. The 11 refers to the 1.1 mm gap - set from the factory, but worth checking during installtion. Tolerance is 1.0 - 1.1mm Link to comment Share on other sites More sharing options...

yewman Posted September 26, 2005 Author Share Posted September 26, 2005 Thanks for that info guys, I do a lot of short trips so perhaps the ngk "5" plugs would be best I know the two plug types in the manual were different makes . Wonder why they specified ngk for one application and champion for another , unless it was an error in translation or typescript. Even now, they could do with hiring a good proof reader before they publish. Regards yewman......... Link to comment Share on other sites More sharing options...
