NGK (3199) BKR6EQUP Multi-Ground Spark Plug

These have 4 instead of 1, and I would imagine burns more of the fuel in the cylinder

You dont gain hp through spark plugs, and the "multi ground" plugs, and the "pulstar" or "diamond fire" are all gimmicks. Time and time again people put these gimmick plugs in their car and then complain that it ran good for a day and now it idles like crap. The best thing you can do for a plug is either a fine tip platinum or iridium plug of the proper heat range for your setup, or a standard NGK copper plug because copper is the best conductor of electricity. Any HP "increase" you see from new plugs is from recovering lost HP from having crappy worn plugs, it is not a modification by no means, nor is any sort of ignition upgrade. MSD coils, better wires, and different heat range plugs etc are all to compliment the demand of modifications that require different ignition components, not a upgrade from stock to gain power.

If say even an intake is 5hp or less and spark plugs and extra 2 and so on, adding all mods together should gain me more horsepower, if 20 or even 10hp up from stock is an improvement for me, im not looking to build a track monster, ppl keep suggesting things like im building a track car. again I have a dd that i want to make perform a little better is all.

And correct me if im wrong, eventhough i dont contest against what you say. I thought there were spark plugs out there, i forget the name, that explode more of the fuel in the cylinder which gives a little more power.

Once the fuel is ignited in the cylinder, that is it, there is nothing that any of these gimmick plugs are going to do to change that. As i sad in my previous post, plugs and ignition upgrades are compliment to mods that require them. For instance, higher cylinder temperatures require a colder plug that allows heat to pass through the cylinder head at a faster rate to prevent flash ignition around the plug that causes detonation or "knock". Decreasing the spark plug gap prevents spark blowout on boosted cars that rev into the high rpms that have a pressure wave of intake air behind the intake valve. Ignition timing adjusts when the spark plug ignites the mixture to allow it to achieve optimum burn at a precise moment when the piston is at the proper angle that is conducive of making peak power. You would be lucky if that intake gained you 5 extra horsepower, if that, and as the filter starts to get dirty that number will decrease some.

This has nothing to do with building a track monster, this has to do with the fact that you chose a 4 banger 1.8 liter engine to modify thats all. This isnt like throwing a intake on a LS2 where you gain 27 extra HP, the gains to be had on small 4 cylinder motors are minimal because they are already efficient at what they do in their stock form. Like i had said previously, when you do modify your car where you actually make power with your mods, you get well outside the ECU and the fuel systems ability to compensate for the changes you made. Honda squeezes these things to the maximum when it comes to fueling, you typically use about 85% of your injectory duty cycle on a stock LS, and honda pushes them close to 100% on the GSR motors as well.

So there is very little to be had by what your attempting to do, stick with the style mods that your enjoying until you decide to invest the money into real modifications, or look at another car all together.

ooooh gotcha! I was actually impressed with my irridiums in my LS. They lasted for 3 years being soaked in oil hahaha they were awesome.

for the OP the rule of thumb is this:

its a japanese motor use japanese plugs like NGK or Denso
Wires people use a whole range, i use Accel, alot use NGK or OEM or even MSD.

Iridiums are great plugs, very heat resistant, and ngk and denso both make some excellent fine wire plugs out of both platinum and iridium. Ive become a huge fan of the fine wire plugs as they seem to idle much smoother and seem hold a much more stable spark when being blasted with methanol and water in boosted applications. Theres alot of people that run their plugs on the side of saftey with a slightly colder then needed plug when modifying aggressively, I went the opposite direction because I just didnt subscribe to that theory. Everyone also seems to frown upon platinum in boosted applications however I have seen my best results so far with the NGK GPower fine tip platinums.



NGK puts out some excellent technical articles regarding the use of plugs in motorsports applications and they really have it down to a science I gotta tell you. I really had no concerns about "melting" platinum plugs in my car running them on the hotter side either, i think its a common misconception that platinum is for long life not for performance.

Well put friend

so spend money on trying to make all motor fast or spend that on a turbo kit and make more power...

Damn talk bout tear a dude apart...lol nah but i get you and i accept what you say. Alotta great information. but like i said before, you forget my application and needs, this is my daily driver... im not looking to drive a turbo to work n school or an all motor track beast. just up my cars performance a little bit. i already upgraded the intake,cat,headers n suspension n drives better then before. ill do new pistons, cams but dont want to sacrifice my fuel economy i have already so fuel system will be the same.

I was Just thinking of timing and air/exhaust flow upgrades for better performance. and even 10 or 5 extra hp is kool with me.
