so i pop the hood today to notice my spark plug cover was crackerd toward the end . Anyone have this issue before i have a evo IX withe basic bolt on's and a tune. Could it have been the heat from the engine itself with a mixture of water = crack. Not sure but anyone heard of this before or know why it happened?

 

Mines cracked, I tightened it a little too much.

 

ii jus noticed it yesterday when i poped my hood too i was liek how the hell that happen i never touched it befor

 

ya same here! ive been meaning to take it to the dealer and tell em they did it when they did an oil change cus i NEVER touched the damn thing, but i just havent had the time to make the trip

 

damn thing thanks for the input happy to know im not the only one

 

Mine cracked couple of days ago. My car is completely stock and never done a spark plug change yet. Just ordered a new one from a JNZ

 

guess its time for a new one. the ARC ones look sharp

 

which end did it crack on, and how big is the crack? that's kind of odd.

maybe someone leaned on it too hard when they were changing your oil or something?

or, i am guessing by your username you are from new york city. (i'm brilliant, i know)

is it possible that it got really cold, then maybe the rapid temperature change from heating up and cooling down caused it to become brittle and break?

 

Never heard of that before but I guess I better check mine.

 

Mine is also cracked by the last bottom bolt.

 

mine was cracked also, I didn't notice it till the first oil change that I did on it....must have been overtightened when it was put together I'm assuming or at the dealer considering I never touched it

 

Mine is also cracked on the bottom right corner. I don't know what happened.

 

its cracked towards the sensor ill get pics tom its a crack from the top to the bottom tho nasty looking

 

i just changed my plugs today and my plug cover is in perfect condition

 

Mine is cracked too on the bottom right. It happened last winter. It has to be the rapid temp changes since I certainly did not do it and no one touches my car but me.
