the plugs that was in the car were Bosch platinum +4 and i replaced them with NGK IX Iridium's i drove around for about half an hour everything is fine for now if i screwed up if some thing is going to happen it would have happen by now right? coz this is the first time i did this. and will this improve my fuel economy right now i get around 16-18MPG

heres pic of the old plugs

new ones

when i took the car for a test it felt a bit more alive don't know weather its my mind or if its actually the plugs

some of it could certainly be a mental thing (the alive part). As far as something being done wrong. It's pretty hard to mess it up but if you did do something wrong you're more than likely going to catch wind of it fast. The only thing that may not is if you didn't bolt the coil down.. it may slip off. But if they are all bolted down you should be fine.

Will it help you MPG... not really sure. It'll certainly help your efficiency. It should help your MPG out a bit but probably not drastically. Good work on taking the initiative and doing the work.

TIP on taking pics of things that small. It's best to hold the object of the picture at a distance and use your zoom to get to the detail, when it's held close to the camera like that it'll have a very hard time focusing on the intended object.
