E-3 Plugs
What do you guy`s think about using E-3 plugs in the RX?? I purchased one for my 5.5hp OHV power washer,and it works great! It always used to have black soot at the muffler pipe,now it burns nice and clean.

Just checked these spark plugs out on www.sparkplugs.com, they are only $5.95 each which is cheaper than the Iridium plugs. Also, I know currently I have Denso IK20's in my car...which has a 0.35 gap, these E3 plugs have a .40 gap, and if you look at others on that website, others are a 0.44 gap. So I was wondering, which is the correct gap for the RX, and would the gap effect performance of each plug?

They recommend the Denso SK20R11 or the NGK IFR6A11.
Maximum gap for a used plug 1.2 mm (0.047 in)
For a new plug it is 1.0 to 1.1 mm (0.039 in to 0.043 in)
I should note that when I used my 4 pronged Torquesmasters on my otherwise stock RX300, I noticed nothing and tried Densos and NGKs again, but after doing modifications (exhaust intake) and then switching back to Torquemasters, the vehicle came alive.

LOL!I went to the Bosch Fusion plugs a while ago and was unimpressed. I put new Denso IK's in and the engine is smooth.

Straight from the manual.

Wow, you're the only success story I've seen with the Bosch O2 sensors. But hey, if it works then great! I was just unimpressed with their plugs and would get random CEL's.
