since i read all over the forum that people dont know how to change out coils, heres my very own DIY

first of all, for those of you that dont know where they are, they're located right underneath the airbox/intake tube, this is what they look like


for those of you with the stock air box, that will need to come out first, i have the k&n intake so it was much easier for me to get to.

Dont forget to unplug your battery first, just to be on the safe side

things you will need.
1. a ratchet
2. a 10mm socket
3. an extension (long enough so that it can reach the nuts)
4. coils
5. beer of choice (not necessary)


aright now open your hood and locate your coils like so


now unplug the spark plug wire, it should come out with ease. should look something like this


now with the ratchet and 10mm socket attached to your extension, remove the nut like so, remember this nut is small so i suggest loosening it up then removing it with your fingers, because if you drop it and lose it, well your *** out and then you need to make a trip to your local auto parts store.


i suggest you put the nut in a safe spot where i wont get lost, and have it next to you for easy access


now remove the coil from the bolt and unplug it from the back, simple clip just needs to be pinched


new coil VS old coil, this is what mine looked like


plug the new coil in and put the coil back on the bolt and tighten like so, i tightened it a little over hand tight about 5-10 pounds, not too much


put the wire back on, and continue to the next one, only doing one at a time so you dont get them mixed up


repeat the same process for all four and you should have em in, in no time!

 

I don't know what I liked better - the ratchet "extension" or the 40.

Mod Edit..
An easy way to identify IF the Coils you purchased are actual OE...

On the side of the black Coil there are three rows of text information stamped into (concave) the coil body, first line is Mazda part number.

Anything else is a knock off product (some on eBay and others)...not originals and can give performance/reliability issues.

Generally if they are dirt cheap they are not OE.

ahahhahaha yeah i tried to make it as big as i could, i literally have like 30 extension, and NO way in hell were they gonna fit in that pic...

 

All the stuff in your first pic look like you bought it from the guy in your avitar. LOL

 

fck buyin em, i clucked that sh*t, a lil crack for some tools goes a long way

 

nice diy dozer

The 40 in the background was like a signature.

 

If you don't get it right the first time, drink a 40 and try it again

 

olde english good **** lol

 

^correction

If you've ever noticed how we do installs around dozers house you'll realize that if you messed up the first time - you should probably put down the 40.

 

yeah like dropping the extention down a live engine hood and sparks flying and ppl getting electricuted?

 

you don't need to disconnect the battery. just don't turn the ignition on.

 

me and dozer got the same husky ratchet set. black chrome FTW!!!!! 5x less corrosive!!!! lol

 

Boobssss

 

where?

 

ha ha awesome extension great write up ill definitely do it now.

 

w00t w00t!

 

Nice DIY dozer

Thanks for making them!
Taking out the stock airbox is going to be a bitch though...

 

yeah i totally forgot about the stock airbox, im running the K&N and i dont have to remove it to get to my coils...thanks anyways

 

No problem Homer ... Dozer...

 

now im ready to do my coils this weekend..... dont know where to find the 40 of OE though, the ghetto is to far to drive to

 

it clearly says beer of choice, that doesnt mean you need an OE

 

so is COLT 45 a viable subsitute?

 

 

SWWWWEEEEEEEEEEEEEEEEEEEET I'll make a DIY video starring BILLY D WILLIAMS and COLT 45

 

I just did this today man it was easy. My car was log overdue for new coils I have noticed a MUCH bigger low end torque improvement. My only question is why did I not change them sooner.
