Hi Car carpros;

I would like to change plugs on my corrolla, and would like to use aftermarket plug to save money; can you recommend a good plug with autolite or boosch; i have been using toyota's iridum plugs which are supposed to last 90 to 100,00 miles but are expensive; that have white deposits with some black carbon buidup.

Use NGK iridium, stay away from Autolite, if you must, use Bosch platinum (single ground) not the +2 or +4.
But NGK is a better plug. Use a dab of antisieze on plug threads when installing.

Look at chart below to see what your plugs look like:

You can buy NGK plugs at most autoparts stores, significantly cheaper than from Toyota.
