Reviews of Denso parts For Business

I put IKH24's in my car as a troubleshooting step earlier this week, due to a low RPM stutter I was getting and knowing I'd been about 15K miles on my stock plugs. They made a BIG difference in my car, much smoother idle when sitting at stoplights, and running a lot smoother under boost at lower RPM's as well. No noticeable difference in engine noise. In my case, this is likely a mix of stepping to a better plug as well as my original plugs just being weary after the ocean of extra power.

kinda smoothed out the car a bit, idles smoother as well.

The coils I replaced with oem and the spark plugs Denso IKH24.

Also, did you even replace the spark plugs with Denso IKH24's? Probably not and that is REQUIRED in order to run correctly.

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.

I switched to the Ikh24 and it really smoothed the car out.

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.

Anyway, got Denso replacement wipers and they're working really well so far. Denso 160-3124 and 160-3118 are the part numbers in case you look into them, 18\" passenger and 24\" driver

Im running a denso they cost a lot but worth it

At this point it's only showing symptoms after idling for 30 seconds or more (and even then not every time), like while waiting at a stop light. Only in first gear, second and beyond have no hesitation. This evening I swapped out the almost new Denso plugs (correct gap) and the problem seems absent.
