TRD/ Magnuson 4.0 Supercharger Tips, Tricks, and Mods

Go solid, the ride was not too much different on my E36 with solid mounts versus my spec.B with poly mounts. Sell the 90a for more go fast parts. Just my .02.

 

When I can keep a sensor from going out that is right where I am at idle.

 

thats what i suggested too. the one benefit to poly will be that it should survive longer on the street. id keep that in mind as the solid will require more maintenance with changing bearings/heims possibly.

 

It depends on your mods really bro. One step colder will offer worse plug porcelain self cleaning characteristics due to the fact that they are not burning as hot as the heat range 6 IKH-22's. That would reflect if you ever checked your actual tailpipe emissions using a BAR 97 3 gas analyzer. You would likely see an increase in hydrocarbons. How much more? I have no clue... however, by gapping them smaller (if they are Iridium's I highly recommend AGAINST that) you allow them to burn hotter so in essence you could counteract the one step colder by minimizing the gap on the plugs in theory.

Gap on these I don't really think about honestly. I just install them and forget them. I burn through plugs too quickly to really care to be honest.

Larger gap is supposed to net you a little better power but too large and it becomes a misfire issue. Smaller gap gets you a hotter burn but will net you some power loss. It's a fine balancing act really and cars like their gaps somewhere between .030- .045.

Your old plugs over the new were just shot is all and the results reflected as such, I bet if you swapped the same out for what you were replacing you would likely find better results than the 1 step colders.

 

I’ll give it a shot. I’m sure it’ll be a blast cruising through wine country on those glass smooth roads. Also picked up coilovers but never got to drive on them yet. Was previously on lowering springs then went with coilovers because I had money to burn.

Since it’s the correct heat range you guys should go with NGK 94122 since it’s in stock on rockauto and mine aren’t.

 

So you're saying the NGK's should last longer than the denso plugs?

Do you know an equivalent part number for NGK that is like the IKH24s?

 

So by that logic though by running a little more gap with the same heat rating could you not be adding more surface build up? Just a thought. I don’t think there is any one really clear answer, I’ve been through a few speed freaks like I said and the answer was much the same. I was also told there isn’t much difference 1 heat level up or down much like it would be tough to notice an issue with fuel that was at 89 or 93 octane when the vehicle is tuned for 91, but you will notice 87 over time. A heat rating of 7 from NGK is probably fine compared to a 6 from Denso, but running an 8 would likely cause an issue long term.

I didn’t actually gap the plugs beyond checking the gaps were at spec. The one that wasn’t was returned for a new plug.

 

I hate part numbers lol. It took me over an hour to find the plugs I wanted from NGK that were close enough for me to be happy.

 

Based on gapping yes, see the above conversation. There is more than one way to skin this cat, if you still have cats I guess lol. I found it impossible to find a perfect match to

$13 IKH24 Denso 5346 Spark Plug

IKH24 though for a reasonable price since those plugs, I learned in my stumblings, are used in the Audi S8/R8 so often are hard to come by from NGK and expensive when found.

 

I bolted mine in beside my winch on my steel front bumper. Really it's easy to pull the lines that lead to the pump, change them out for new flexible lines, and relocate the pump to anywhere that's at around the height of the stock setup.

 

Just a thought on this from the chemistry end. Ruthenium is really similar to Platinum in terms of reactivity in a lot of chemestry but it has the properties similar to Iron in terms of electrical a lot effects. I'm guessing a Ruthenium plug would be even more expensive then an Iridium plug, since the metal is even rarer on earth than Iridium and produced as a byproduct, and only offer a higher conductivity than Iridium for advantages. It will probably wear a bit faster than Iridium too like a Platinum plug would.

 

I keep thinking about painting my calipers red ... but it's a stupid idea for a truck and only belongs on fast cars, right??

 

I just cheated and looked at pictures. Not sure what the trick is but NGK and their cross reference numbers annoy me to no end.

One of my guys sent me an article showing the science behind it. He says just based off science NGK isn’t spewing BS by claiming higher conductivity etc.

 

Personal opinion. Red calipers are as played out as plastidip.

 

Do your rock rings instead. Mine came out good. Though they’ve gotten a little beat up by now.

 

That's what I said too. Basically Iridium is great for being hard but it's not as conductive as Copper or Platnium. By the science Ruthenium will behave electrically Iron/Platinum, so more conductive than Iridium, but with possibly a hardness closer to Iridium than Platinum. Should be a good combination but if the cost is crazy like race plugs it won't be worth it over Iridium.

 

Thanks @Kelvin, that's what I needed to hear.

@snowsk8air2 yours look killer, perfect with your build. On my black truck I think any color would stand out too much, and black would blend in too much. Hmm...

 

This with gloss black calipers gets my vote. Black lugs wouldn’t hurt either, unless you love your impact gun.

I picked up some Kyo-ei black lugs in japan and idk what kind of space age metal they use but one of them stripped a thread off my ARP stud. Fixed it with a die.

Be a pal and try them out for me

Ruthenium is supposed to have a higher copper content but yes, like you said with the hardness of Iridium.

A guy on the Lexus forum tried out the plugs on his almost stock car and he says mashing the throttle at a 40 roll he can get the traction control to engage. I have a hard time believing that but the quicker ignition could help, I suppose?

 

Thanks for the input man!

 

I have a really tough time buying into that lol. That's probably another case of replacing copper plugs that have gone bad with new plugs of any sort that are correct for the application.

Hmm not scientifically correct! I'm just kidding around with the exclamation point but, by the science, it's that Ruthenium has a lower resistance at a given voltage than Iridium. Being an element it has no copper in it unless they are alloying it with copper, which is possible. Since Ruthenium has a lower resistance than Iridium, it'll give a stronger spark for a given voltage across the same gap. Nothing that has a lower resistance than copper will hold up to the temperatures and voltage in this application. Copper is soft though so it erodes quickly hence the shorter change intervals than other metals. Actually what make Ruthenium probably so good in this application that it tends to hold it's conductivity at higher temperatures. In layman's terms that means it should be a very consistent spark even at higher combustion temperatures.
