Plugs Ngk bcr8es they are gapped correctly for the sr and are heat rating 8 and super cheap cause they are copper.
No need to take off the bottom hose off the rad just undo the drain plug on the rad at the bottom.
Don't go crazy with the boost or you'll melt your engine.
Pop in a uprated fuel pump and don't buy a second hand one.remove the restrictor in the hose going to your wastegate to increase boost a bit it won't increase by much but it will still be safe
