vs
Spark plug Autolite or Denso
The coils I replaced with oem and the spark plugs Denso IKH24.
Pros: replaced coils and plugs
Vehicle:
Volkswagen
Part number: IKH24
Also, did you even replace the spark plugs with Denso IKH24's? Probably not and that is REQUIRED in order to run correctly.
Pros: required to run correctly
Vehicle:
Volkswagen
Part number: IKH24
On 02/18/2016 I switched the plugs with the Denso IKH22 at 15800miles. Jetta is more rev happy. No slow down throughout rev range, and no more pause hesitation between 3.8k-4k RPM. Just pulls, and pulls even harder. Also idle very smoothly.
Pros: more rev happy, no hesitation, smooth idle
I switched to the Ikh24 and it really smoothed the car out.
Pros: smoothed car out
Part number: IKH24
So here is my experience with gaps on this engine. The wife 09 Passat was misfiring so I decide to replace the plugs. I buy Autolite double platinums which were gapped huge. Turns out the 0.032 gap was not correct after all and it should have been 0.028. Big difference, this baby flies again (GIAC tune).
Pros: baby flies again
Cons: misfiring, gapped huge
Vehicle:
Volkswagen Passat
Replaced my OEMs this summer to Denso K16GPR-U11 and has been getting really good mileage and smooth idling since then. Now planning to try NGKs next time.
Pros: good mileage, smooth idling
Vehicle:
Volkswagen
Part number: K16GPR-U11
Changing the plugs from bkr7e's to denso ik27's helped a bit too.
Pros: helped a bit
I said from the get go that the Densos were running like ****. Especially at wot around 110mp/h it felt like the engine was hesitating and lacking power. Idle was smoother with the Denso though.
Pros: smoother idle
Cons: engine hesitating, lacking power
When we got our 535xi one of the first things I did was visit the local parts place to buy new spark plugs for the N54. After driving the car a while and visiting many BMW discussion boards I learned most folks have a very low opinion of them
Cons: low opinion
Vehicle:
BMW
Just install my today, is it just me being paranoid or else? the engine noise sounds louder and it's very noticeable. Has anyone felt the same way? by changing out for these spark plugs, does it make any advantage performance wise? btw i am pretty sure the installation was good and not misfire or anything likes that. just more engine noise and not a good noise.
Cons: louder engine noise, not good noise
