NGK spark plug question/help!!!
If i were to get a pair of NGK BUR7EQ Leading , and BUR9EQ Trailing...will this be better than those $1.99 spark plugs from Kragens?
Also, do i need new spark plug lines to make it better?
Whats tha difference between Leading and Trailing??
Is the rotory engine spark plugs as easy to get access too and get out as the piston engine ones???
Where is it located ???
( sorry, never messed with spark plugs before)

You can pick up the NGK plugs at Advance Auto, they're like 5 bucks a piece. Expensive for spark plugs, but considering you only need 4, not too bad.
They are easy to reach, but I'd recommend wearing gloves when you do it, or you'll end up scratching your hand up.

My personal method is to put the plug socket on the plug, THEN attach the ratchet - it fits a lot easier, and turns it from a royal pain in the rear to just another plug change.
Also, get used to it. Rotaries eat plugs like none other. If you haven't changed the plugs before, you'll probably feel a big difference. Even just cleaning mine seems to help for a while.

remember to follow the excelent method of only changing one at a time so you don't make a mistake.......or just write down the order on a piece of paper. I took em all out assuming it would be easy to find a diagram in my manual....ended up having search through thousands of forum posts to get the correct firing order.

tahnks guys, i picked up a set of trailing and a set of leading for 4.99 each at Kragens.
When i was getting ready to change my spark plugs, i found out tha it was tha same ones that i bought... is it a better idea to change them or should i just clean the old ones and reuse them ( heard sumthing about cleaning tha spark plugs )???

Ok, a few comments on questions above.
For a while, with my rebuild, I was pulling the plugs every other week to clean them. I just used a wire brush and scraped all the crud off. Seemed to make a noticeable difference.
At this point, I pull the plugs every few thousand miles, or when I get bored. They're due for replacement, actually. 4000-5000 miles on them. It still runs fine, but I tend to err on the conservative side, at least right now (fresh rebuild, and I don't drive it often anymore).
Firing order on the plugs is actually very, very simple to figure out.
The rotor towards the front of the car is #1. The rotor towards the rear is #2. And if you have a 20B, you should know enough to figure it out for yourself.
The Top plug is the Trailing plug. The Lower plug is the Leading plug.
The coils have L1, L2, T1, T2 in the plastic near each post. It's really simple to figure out.
Also, technically, you can swap the L1 & L2 wires without a problem. The leading coil fires both plugs at the same time (waste spark setup). I wouldn't, just because you might confuse yourself down the road, but you can get away with it. If the trailing plug wires are swapped, the car doesn't run well at all.

Oh the stupid things I do when I'm not thinking right. I have this nasty habit of taking things apart and then forgetting how they go together. Oh well, I just learn the hard way

Yeah were gloves you do scratch your hands in there. Use an extension of some sort for the wrench this way you can get more leverage. And always carry your tools with u just in case your car gets flooded.
NGK rocks lol
