Dont think these plugs are good anymore
 

First problem is they are Boosh POS plugs

Im goin to email the co. They dont even have 1k miles on them

Umm if you ask me it looks like you have motor trouble not spark plug trouble. 2 of the plugs look good, but you may want to make sure you don't have issues in the cylinders that the 2 plugs that have the tips eaten off of. How much timing are you running and do you have knock? Any fueling problems, like running too lean?

I did have a code of bank 1 too lean. When i pulled the plugs out of cyl 1 and 3 they wasnt tight. So i think that couldve been the reason. I have no knock or fuel issues

Those plugs aren't burnt due to manufacturing defect, they are toast because of the motor is my guess. Will be curious to see what the newly installed ones look like. Do you have a way to log the car using up tuners software?

The one on top really looks bad. You may want to run a compression test while they are out.

do you have an lsj? cause those are not the correct plugs for an lsj. they are the wrong seat type (tapered vs crush washer) and the wrong length. lsj plugs are a standard 3/4" reach, those look like a 1" reach. they look like the plugs that would be in a 2.2l or 2.4l.

you have something else going on there as well. could you stand the plugs up and get pics of them, id like to have a look at the porcelin

The porcelain on the top plug is toast and what bothers me is it looks like heavy oil/carbon buildup on the plug also. I have no clue how the car could have ran worth crap.

I4 engines only have 1 bank, you're running lean. Also address the concerns about the correct plugs for an lsj.

looks like this dude has an SS/SC. so there for sharkey you are right and those plugs would be wrong if in fact this is his SS/SC. this is where research and a torque wrench come into play as a prime example, esp if the plugs werent even tight let alone the wrong ones.

You seem to be correct. 2 of those plugs have the ends of the threads eaten away at, which tells me there were in the combustion chamber possibly.

Def the incorrect plugs for an LSJ.

I went to autozone lastnight. They tried to give me the wrong plugs again. The guy said they will fit 2.0, 2.2 and 2.4. I blew up on the guy. He looked it up under a 2.0 and they were def the wrong ones

I dont have a tune on the car

^These are the correct factory plugs you want...

You can also snag up NGK BKR7's at autozone for cheap and are also a plug that works on the LSJ. Never rely on a parts guy behind a desk.... Especially one at Autozone.

This i why if i ever go to a parts store, i always write down the exact part number i need. Gotta dummy proof it.

NGKs work for LSJ too? I should see what those cost on Amazon.

Yup look at post 19

When I had an lsj, autozone stocked the correct ngk plug. Just a thought

Just go ask for a BKR7E plug, don't let them look it up by car.

If you have to though, an Evo, from like 2006 or whatever, calls for those NGK plugs stock.

some parts guys ive found cant figure out what an ngk bkr7e plug is. if thats the case, give them the stock number, 4644
