plfr5a11

    Can I use LFR5A-11 spark plug for a Nissan Sentra when Nissan recommends PLFR5A-11?

    Would it affect the performance a lot? Also for PLFR5A-11 the recommended gap is 0.043 in. Should I use the same gap for a LFR5A-11 also? What happens if by mistake the gap is set smaller (like 0.038)?
