Best spark plugs for EJ22?

What are your choices for the best plugs to run in an EJ22 SOHC- Iradium? Platinum? What brands are the best NGK? Denso? Bosch?

NGK. OEM recommended.

Regular NGKs are just fine. Platinum and Iridium plugs were designed for much longer service intervals. I've tried Iridium's on my 2.2 and could not notice it performing better when new than the regulars when new. I have regular NGKs in there now.

I'd do Iridium's again if they were supplied with stickers the way K&Ns air filters come with stickers. Then my car would be wicked quick.

The Subaru dealer I took my car to said that they have luck pulling out platinum plugs and putting in standard ones to fix some problems NGK standard ones... I have the platinum ones currently

when i was having a phantom misfire i went from copper NGKs to platinums, to iridiums and back to coppers. the coppers just dont last long in the AZ heat and such, so i put NGK platinums in the GT and put the iridiums back in the wagon. theres no real noticeable difference performance-wise between the three that i can tell, but the platinums do last longer, and arent too pricey. going from a standard plug to an iridium in my truck was actually noticeable tho, so mebbe it matters how many cylinders you have.

^i agree with the platinums being very good (going back to those in the winter) the iridiums are too hot a plug, the copper v-powers are the best for a stock ignition imo.

Sounds like it will run well with any type of plug, some just last longer than others. Is the NGK the brand of choice for most people, or are most brands sold perform equally as good?

Regular NGKs in my 95 and NGK V-powers in the old tleggy.

We all agree on NGK's as they seem to work better than any other brand in our cars. People have had phantom running issues and the only fix was the plugs being swapped out for NGK's.

 

I've always run the NGK platinum plugs in my Subaru's.

My car started missing at 160.000ks and I changed the plugs..... They were original. God, they seem to last forever these days. The cars still on the same leads and runs like a dream. The same leads with 222.000ks on the clock. Amazing.

One of the first things I buy for every car I've owned since 2003 has been NGK plugs. Their reliability pays for itself let alone the mild performance upgrade you can achieve when combining new plugs and wires on a used car. I've had them on my Mazda for 115k miles and I feel that they finally could use a new set. That's pretty impressive considering that all that mileage was within three years.
