Spark plug Denso or OEM Subaru

Changing my sparkplugs for the first time (32k miles, yes it's early but I got a great deal on the plugs) and found that the stock plug in cylinder 4 actually had a ground electrode defect and was significantly thicker than normal. The car runs stronger than it ever has as this was likely causing extra timing pull.

Densos. Buy them off rock auto.

The Denso IHKs are my go to for the last 10k on their tune.

Either one, but I found the Denso to be cheaper and easier to get. No issues with them.

You can usually find DENSO IRIDIUM Spark Plugs , which are the OEM Supplier, for about $15 each at any Advance Auto or other major auto parts store.

Yesss got denso coils and spark plugs off their site and they have been great

im at 95k with the original plugs. no issues

We just got the 60k service done (spark plugs) and it still does it.

Skip them, they are junk and a waste of money.

Get a good single platinum plug like the Denso 4511.

the tips of the IKH24s break off in expensive TTRS engines.
