seems like I recall somebody questioning the cheap spark plug choice and being immediately poo-poo'd for suggesting such an idea
as much money as you put into these does it really make sense to not use the best spark plug you can get?
You can get the NGK Iridium Racing plugs made specifically for the Renesis; Part No. 3795 (L) and 5009 (T), both in 9 heat range. They are pricy @ approx. $60 each, but it's the best plug you can put in a hipo Renesis, the correct lengths, etc.. I did manage to get a whole set of 4 in 9L/10T for $80 shipped off Amazon back in January before they caught the pricing mistake. Wish I had bought the entire lot available, lol.

9K, do you figure out what intercooler u use? I didn't go through all your threads, but do you stick with your stock greddy?

I am using the stock Greddy intercooler, no need for an upgrade.

That's actually something we need to get data on, Scott and I have similar setups. I have a larger compressor housing and a larger (cheaper) intercooler. Our intercoolers are also in completely different areas.
Both him and I need to get hot and col side temps for the intercooler and see what they are at. Most likely he will have better temps due to the greddy intercooler being better quality but its something to consider.

what intercooler do you have now? the size? I am planning to get the same measurement as greddy on, but thicker...I have gt35 turbo...

hi shady, I have a big intercooler too, and we can see in the comparison in a thread which Brettus created. I have been working on my car a lot, and I did research about the intercooler, realize that I have a big intercooler, 31"x11.75"x3" but if i noticed, 4 inches of the top intercooler get blocked off by the reinforcement bar..i think the stock greddy is good because the whole intercooler get fresh air...do you feel the different with bigger intercooler?

Can we use the NGK (3795) R7440A-9L in all 4 positions?
These have a 2mm longer reach than the 5009's.
5009 - 19mm reach
3795 - 21mm reach
Wouldn't they have to be spaced out?

No, the L plug is longer than the T plug. That's why they have both. You can run the T plug in the L position as was mentioned earlier, but the shorter length places the spark event in a less than optimum location. You can use a spacer, but why would you want thd hassle and bother when both are available from 9 - 11 or 11.5 range? If you leave the spacer gasket out it will be a fubar situation.
And like was me tioned in the previous post, it probably makes the most sense to use the L race plug and the T OE plug for a street car

Looks like my bad on the T side. Apparently they discontinued the 9T plug. They both used to be available in 8 too, but I knew those were discontinued a few years ago.
So yeah, run 9L using the racing plug and 9T using the original factory plug

From what I can find the the 5009 is a 10 heat range and the 3795 is a 9 heat range.

Where are you getting that those plugs are available in different heat ranges?
The part number changes as the heat range changes.
The OE Trailing and Race Leading isn't a bad idea at all, I may just do that.

I have an old pdf of all the NGK plug numbers. When I just checked a newer version I saw the 9T is no longer listed. The part numbers do change with the heat range. The model number is R7440; R7740A for leading and R7440B for trailing. Each would be followed by a dash and the heat number
