Coil Pack Question - Different Coils

[R34_Bunbury]

Hello All.

I recently got myself a R34 sedan, and have an annoying miss when it gets hot. One possibility is the coils packs failing which is common on the Skylines. I had a look at the coils and the car has two types of coils in it. Looking on the forums 3 look like they are Splitfires and the other 3 look like Nissan OEM.

My questions are : Am I correct on the different coil types.

Can having the different brands cause issues.

Do I only replace the OEM with splitfires or do i replace them all?

My final question is why would somebody just replace three not all of them, surely a skyline owner cant be that cheap.

Thanks R34_Bunbury

Hard to tell with the pic but the one on the left is definitely not standard Nissan. Having two types of decent coilpacks (as far as SAU is concerned the only ones that are any good are splitfire and OEM) would not be an issue as long as they are still working fine.

My advice is to let the car warm up and then disconnect each coilpack one by one at the clip and listen for the engine sound to NOT change. When you take a clip of and hear no change from the rough sound you know that is the coilpack/spark plug that is at fault.

Had a look at the spark plug condition yet?

The one on the left is not OEM nor Splitfire

Personally I'd have 6 the same

Thanks for all your replies

Will try the disconnect coils one by one trick if I get some time next weekend, will also look at the plugs. I too would prefer all the same depending on what I find will I will replace them all with splitfires as they are the SAU standard.

Since it's an used car and you've just taken ownership I would just fork out some coin and replace all the spark plugs followed by a brand new set of coil packs.

If you're after straight plug & play a new set of Splitfires would be the best options, if you're into DIY and a tinkering, go with a set of LS coils.

I would avoid any other coilpacks that aren't OEM (new) or Splitfires. I've used other brands and they're all garbage once you start putting down some decent power, they all fail.
