Anyone else measure the gap on an Iridium Power only to find it narrower than specced? I bought a few IKH20 plugs that were supposed to be gapped to 1.1mm, but proved to be 1.0mm using a standard wire gapping tool. So I did what was sensible and re-gapped them. It only occured to me much later that the U-groove probably accounts for the missing 0.1mm.
Thanks foir the video. Denso have a new TT Irridium spark plug, so now theres 3 to choose from. I just received a set but not fitted yet. Interested to see the old spark plugs condition
@3:20 you mention you likely won’t notice much of a difference performance wise in actual driving conditions since the performance improvement of the Power plug offers is a relatively small advantage. With that said, why would someone not go with the longer lasting Tough plug if you gain no perceivable performance gain with the Power plug? If Power was a noticeable gain I understand the argument but you made it sound negligible in the video. Just looking for clarification. Thanks!
Hi, really depends on the application. From the data Denso supply the gains are marginal, I haven’t managed to run a dyno test to confirm if there is any noticeable power increase in the power plugs over the tough. The type of car you’re using them on will be the biggest variable. If you’re running a highly tuned car with lots of boots or high compression this will affect the quality of the spark, so in that instance the power plug may offer more gains. Also the condition/setup of the ignition system. Older cars with HT leads and distributors may notice a more significant gain as generally they have a weaker ignition system. So you might go for the power if it meets your engine build requirements. On an average car doing more than 10k miles a year, the tough is a no brainer really with the extended life span. I’m doing less that 2000 miles a year so the power plugs are a more sensible option as I’ll be changing them due to age rather than mileage anyway. Hope that helps
Short answer is TT plugs are designed for waste spark systems, 1 coil / 2 cyl where plug wear is essentially double. Won't hurt in a standard 1:1 coil/plug setup but little benefit either.
I have a 660 cc Toyota Pixis. It's a daily driven car over short distances but yeah it goes like 20k plus Kms an year. Which plug do you recommend? Iridium power or Tough iridium
@@waleedakhtar3437 hey, I can’t remember off the top of my head but, it’s marginal really. If you go the the Denso website, they have some data which compares the spark plugs 👍🏼
From memory the iridium twin tip is better if you are after fuel economy and want something that will last. All the data is on the Denso website am.denso.com/plug-global/
@@GarageTechAutomotive i dont want last longer i just want any plug which can save fuel and give extra poer , i wonder why website says iridium tough give better fuel average and i s costly, but you said twin tip is better for fuel average
@@furqankhan3930 only have experience with this on my 140cc mower. Gapped the IK16 plug to spec and tried it out. My mower since new would bog or stall out in tall grass especially if I used self propel. Also, I usually bag my grass but I couldn't believe how well it managed on tall grass and weeds. It never bogged down to die at all! And this is with a dull blade! I use a full tank for tall grass but it got it done on a 1/3 tank of gas. I'm sold on these spark plugs, gonna buy more!
@@GarageTechAutomotivei have non efi 1300 cc whichone is better iridium ix, iridium power , iridium titanium tip, iridium tough or double platinum plug to reduce fuel consumption and to enhance power and performance
@@furqan9499 to be honest, unless you are running a high performance engine with high octane fuel etc. I don’t think you will see a huge amount of difference between them all. The tough will last longer so if you’re doing high mileage 15-20k miles a year I’d go with that, if lower, like less than 10k I’d go with the power plugs
@@GarageTechAutomotive i am not doing high mileage i need to reduce jus fuel consumption in our state there is huge energy crisis petrol is going hitting day by day and sometimes nifmal fuel quality no good and not bad s i thougt to use high ictane after carburetor maintenance so just prefer me any best plug ,on the other side i read on denso website that denso iridium tt (twin tip) can reduce that 2.5% fuel consumption go read about denso iridium tt then recommend any one plz plz
@@furqan9499 I’d go with iridium twin tip but most importantly, you will need to get the carburetor tuned afterwards. There’s no way the carburetor will know what plugs have been fitted. The garage will need to measure the exhaust gases with a gas analyser to check the HC (hydrocarbons). This is basically unburnt fuel. A good garage will know what to do.
I have a 2007 E550 with 150k miles and stock plugs still inside I think. I was wondering What would be better choice. Denso iridium power 5353 ixuh 22 plugs or ngk 5353 iridium ix plugs?
I’ve ran iridium power for 60000 miles completely fine to run them till failure - Hemi 5.7 even drove from Il to Ca on them when they had over 40000.

Thank you, great job, excellent information.
Please, spark plugs for Denso are manufactured in Indonesia, with the same performance as mine, manufactured in Japan. Thank you.

10,000 miles on a HEMI with 16 spark plugs is not worth the cheap plugs because the labor involved is far more expensive.
I thought they last longer and standard copper plugs lasted 12k or longer

@@GarageTechAutomotive yes that makes perfect sense, thanks for the additional feedback!
could you compare TT vs tough vs power vs Iridium?

I’d go with the tough if it’s a daily driver, they last so much longer 👍🏼
@@GarageTechAutomotive thanks buddy
One more question.... In terms of percentage, a gross estimate, how much better are iridium power on fuel efficiency as compared to tough iridiums
@@waleedakhtar3437 hey, I can’t remember off the top of my head but, it’s marginal really. If you go the the Denso website, they have some data which compares the spark plugs 👍🏼
can you tell me which one gives best fuel average iridium power vs iridium twin tip vss iridium tough vs platinum twin tip

I got them online, if you do a Google search you might be able to find a local stockist. 👍🏼

They're both equally excellent plugs. I highly doubt you still have the original plugs at 150k, lol.
PL sir were to buy original lrldium spark plugs in Lagos
The *Tough* and *Long Life* appear to be different names for the same part. Maybe just a regional marketing thing?
(-) power = Ni Alloy 20000km , tough = Platinum 100000km.
