Hi all! I have a 1990 Corolla LE Liftback, and I just changed the spark plugs today. The owner's manual recommends that I use NGK BCRE527Y plugs. I was recommended a set of NGK BKR6EVX when i sent in my car for servicing. I know there may be issues with the temperature rating, so I'm worried that these plugs may not be the right ones. Can someone please offer some advice on this? Appreciate your help.

Forgot to mention that the engine wasn't as smooth as it was before. I just changed them back to the old ones this morning. Immediately saw an improvement...you're right, can't go wrong with the ones that the manual recommends. Thanks.
