aluminum spark plug repair inserts

who or where do I need to call to get the aluminum Timesert spark plug thread repair inserts? I have been told to only use the aluminum but all I can seem to find are the steel. Called Timesert and they gave me dealer numbers to call and they didnt even believe me when I told them they made them in aluminum. And do I really need aluminum

 

ive used the steel ones for years without a problem..Dave

 

i have only seen the steel ones i have never had a problem either

 

We've had to use the steel ones in the past, have never had a problem with it.

 

When using the steel inserts, have you guys noticed a EGT to spark plug color change. Like the plug won't show the heat like it used to.

 

I have only seen the copper ones from Timesert ?????

 

If you really want aluminum,

Use these:

i mis spoke mine are copper also not steel

 

Thanks for information The steel inserts I have are cooper in color but a magnet will pick them up . I was told the spark plug would not read correctly with the steel. Thanks Eddie

 

mine were copper also..Dave

 

My mistake then, I thought the copper colored ones were copper. I've used them 3 times now and cannot tell the difference ?

 

i have heard that also so are the ones that look like copper! copper are steel
