I know Tony G only told me about 9 times but which spark plugs was he using. Anyone? I know they were NGK-R's just dont remember the plug number.

NGK BPR7ES is what I use, it's 1 range colder than stock

Matt,
I'm not sure which plugs tony was recommending, but I was/am using the NGK IX Iridium's, part no# BPR6EIX, Can get them from ngk.com for $6.95ea.

NZ951

I am using those too Wes, good timing Matt! I am about to get some new ones also and was about to search for them, look forward to getting the number!

I'm using the same as David (upon the recomendation of Tony and others). Maybe I didn't really need to go one range colder, but it runs great with them and some new wires.

I went with Denso plugs just to be different

Denso W22EPR-U

I actually bought them because they had the "U-Groove" electrode. This is supposed to fight quenching and reduce the chance of detonation. I have no idea if it works, but the equivalent NGK, BPR7ES was a traditional style, instead of grooved. I figured it couldn't hurt.

They performed like champs out on the track, but I haven't pulled them to see what condition they are in.

If I remember correctly TongG got a 5-7 hp dyno gain with the NGK plugs he used when compared to other new plugs they tried...

MySwiss

Tony recommended the NGK BPR 7ES or even the BPR 8 ES, which is what I'm now trying . Hoping to solve some missing issues between 6800rpm and 7200rpm.

MySwiss!!!!!! OMG you live! I am after the updated hose running from the intake manifold (then under the manifold) to the brakebooster, ISV and venturi deleted... can you help?

MySwiss

NZ951. Yes I'm alive . Unfortunatly for some, I took some time off with the family, and our shop was closed for a while (sure feels good to take some vacation time sometimes.....had to live my life off the Rennlist sometimes!!!)

What seem to be the problem??? We carry a blue silicone replacement hose for that purpose. we have a complete kit for 70$ plus shipping which includes the following
1) brake booster hose
2) crank breather hose
3) vacuum hose
4) 6 brass T fittings
5) 4 intake manifold gaskets
6) 2 updated idle stabilizer hoses

NZ951

Ok, dont have a problem as such, but I cut the old brake booster hose to fit onto the intake manifold, but the big black rubber hose wont bend under the manifold, so I am looking for the shaped hose that will come out of the intake, bend under the manifold and go to the check valve connection where the small vac line t's into. I have a catch can setup already, dont need that hose, have an LR cacum hose, have 10 more brass T fittings than I need, have new manifold gaskets, and dont have an idle stabilser anymore. I am just after the hose from the intake manifold to the connection described. Can you help? I am not sure what "1) brake booster hose" is excatly. Is it both hoses from the check valve to the brake booster and one from the check valve to the intake manifold?

a bit warmer plug for me (Michigan) BPR6ES

Just put them in this weekend WOW NGKs are the BEST I have to hunt for them for the CHevelle but well worth it (feel)

Anyone have a dyno run on NGK vs Other?????

NZ951

PS I really like the sig MySwiss...

MySwiss

NZ951. Just get your self a 3' 1/2inch regular thick wall black (or any color) hose. It will work just like factory and cost you a hole bunch less. If not i can get you the factory hose.
