The money you spend to purchase your car only represents a portion of the cash outlay necessary to keep your vehicle running properly. You’ll also need to allocate part of your budget to periodic repairs and replacement parts. Both are inevitable.
Basically you want similar plugs as stock, but a cooler heat range and a smaller gap. The stock plugs are NGK BKR6EP-11 (2978) and are platinum tipped and have a .044 (1.1mm) gap. The ideal NGK replacement for a modified Supra would be the BKR7E (6097). It is one range cooler (the ‘7’), is non-platinum tipped (the lack of the ‘p’) and has a smaller .0315 gap (lack of the ‘-11’). This plug is also called the NGK 6097 and they are fairly inexpensive. Platinum tipped plugs are not desired for high power applications, Iridium plugs are more preferred. Unfortunately their doesn’t seem to be a BKR8E which might be better for high-HP Supras.
The quality of DEF is very important. Its quality is dependent upon the kind of DEF dispensing equipment used. There are certain factors that need to be considered while purchasing dispensing equipment. Some of these factors are market standing, price, functionality and durability.

Subsequently after all pipes are connected, begin fastening each section to the 1st. Apply an ample amount of torque on each bolt to make certain it is tight.
If you smell something that resembles rotten eggs, that usually signifies a problem with the catalytic converter recyclers. In this case, you may be safe to drive the mechanic to fix it and the repair bill won’t be too costly, but you’ll want to get it fixed. It will continue to smell awful and you won’t be able to get it certified. It also won’t pass an emissions test.
How many miles does it already have on it? If you’re looking for a specific make and model of car, do your home work and see what total milage that car is good for in its life time. Also look for what kind of gas milage to expect, and were there any recalls for that car that year.
You have to cut the tube on either sides of the converter. Use the reciprocating saw as well as the metal blades. Leave an allowance of 2 inches of tubing on the ends of the converter for the needed spacing. Allow the catalytic converter to fall by its own self but make sure you are not underneath it when it falls.
