They come pre gapped.
Most of us use Shell Rotella t6 5-40 and a good oil filter
You may want to clean the MAF sensor.
Read the DIY's threads on here.
I bought a 4-pack of the NGK iridiums that were supposedly for the LGT, however when I double-checked the gaps they were all roughly 0.040". Our gap is supposed to be between 0.028" and 0.030", correct? Just a friendly heads up.. don't always trust the pre-gapped plugs.
Max, have you heard of running an RX-8 oil filter?
