iam looking to changed for the first time my 04 car spark plus. which ones are the best in the market ?????????

 

Think the original ngk iridium oem aree pretty good for 100 k, so why not stick with those. How many miles do you have anyway?

 

Not to jump in I have 150 k on my 04. How big of a problem can it be to get em out? This is really the only maintenance I have neglected.

 

my car has just 80 k. i want the best for my baby

the originals are the best to use for replacements. just be sure and check the spark-plug gap before installing them - sometimes they can be off by a mil or two out the box.

these are pretty easy to replace - just be sure you have a long enough extension for your Spark Plug socket. but if you are inexperienced with Aluminum heads, there are some precautions you have to take.

Make sure the engine is stone cold when you remove the plugs.

(Im not sure if the lexus heads have the steel sleeves for the plugs or not, but this is good to do either case.)

be sure and Install the new plug in the cylinder after coating the threads with anti-seize compound - Don't skip the anti-seize when you are dealing with aluminum heads. The steel of the spark plug and the aluminum of the heads can react, causing corrosion, making it difficult to remove the spark plugs next time, and possibly damaging the head.

when you reinstall the spark plug wire boot onto the spark plug, Use a little dielectric grease or boot grease inside the spark plug wire boot and this will make it easier to slide the boots on and keep them from sticking the next time you remove them.

 

thanksssssssssssssssss

 

I want to add a caution - Pay attention to the force on your wrench as you are unscrewing the spark plug. If it begins to get harder as you unthread (instead of easier) then the threads can be galling. If you keep forcing it you will destroy the threads in the cylinder head.$$$ The fix is to run the spark plug back in, then back out, repeating until you can completely unthread it without excessive force. Each cycle in-and-out should allow the sparkplug to come out a little further as you slowly clear the threads past the galled areas. If you were using an air wrench (horrors!) to remove the plugs you will never notice this until the damage is done.

 

thankssssssssssssssssssssss a 10000000000000000000000000000000000000000000000 for the info.

 

Another tip, to loosen first tighten to break any grasp, then remove... helps prevent galling
