What year is your Blazer? I looked up K and N but they only have intakes for 1994 and newer. Will these also work on the 1993? Thanks!

I'm thinking about getting the K & N intake kit for my 2000 LT. I've seen one on a Sonoma and they are impressive, when you hit the gas it sounds like all the air around you is being sucked into the intake. It's sounds awesome. I can imagine how much gas it saves.

Right now I have just the K & N replacement filter in the blazer, but I got to get the kit.

the CPI Vortec was made from 1992-1995.

I have the same engine as you.

So what year did you order the intake for? 1994? Like I said I looked up to order and they only show for 1994 and newer. Also, did you have to change anything such as oxygen sensor or anything? Thanks for your help!

1992-1995 have the same intake for the Vin "W" CPI Vortec.

Thanks for all your help!

My pleasure, I love my intake.

I was just thinking. Can't I use the stock intake tube directly from the intake box and add an open element cone filter to the stock intake tube as opposed to buying the full system(tube and filter)?

Not really, the resonator which is the flap that attaches to the fan shroud slows air flow.

You can make your own intake using PCV pipe from home depot and a little workmanship. Just do it right and also replace and install the IAC sensor into the new setup.

Forget it. That is too much work for me. I will just get the kit. Thanks!

Here is a haow to for the home made intake for the 1992-1995 CPI.

What is the IAT boot?

It's the rippled boot that attached to the front intake of the engine.

On the underside is the IAT. Intake Air temperature sensor.

Does the IAT have to be replaced with the K&N kit or just the homemade kit? Do you recommend the homemade kit or do you think I should go with the K&N kit? Thanks alot for your time and answers to my questions!

The IAT is a sensor, you have to use it AT ALL TIMES.

The K&N is really nice and very easy to install.

The home made one is really really cheap to make.

Your choice.

What do you recommend? The homemade or the K&N? Do I have to replace the IAT sensor for both kits or just the homemade one? Thanks for your time and answers!!

Sorry I posted this question twice I didn't see the second page!

Sorry I posted this question twice I didn't see the second page!

About the sensor, I should have worded the question differently. I meant do I need a new sensor when I change the intake or can I leave the old one in? Thanks!

Leave the old one in seeing you will be reusing the boot when you make the homemade one.

With the K&N , you will be removing it from the stock assembly and installing it into the new intake.

I have a problem. I called K&N and the guy told me they don't make a cold air intake for 1992-1995 S-10 Blazer. I told him you have one and he diidn't believe me. What is going on here? I am confused! Do you have a part number for that thing? Sorry to drag this on! But thanks!

Teheheheh!

Not a problem, sometimes I really go overboard with the help but I always learn as I go also.

I was looking at the picture you have on here. Is it just the picture or is that intake hose really that close to the alternator?

It is close but it never touches.

I'm gonna order it right now from ebay. Thanks!

not a problem, enjoy it, I know I do.

Growls nicely when you floor it.

Its on the way! If I have any questions when I am istalling it I will ask you. Thanks!

Just follow the instructions and you will be fine.

One more question I forgot about not pertaining to the intake. My Blazer has a very minor idle roughness to it. Enough where you feel it. We have owned it for 2 1/2 years now and love it. It has always had this idle. Is it something to look into or leave alone. I used injector cleaner when we first got it but that didn't do anything. Just wondering what it could be. Thanks!

Ever done a tuneup?

Ever done a tuneup?

Nope. Can I do it myself or is it a big project? I'm not a big mechanical person. My mechanical apptitude is tearing the carb off a minibike and cleaning and putting it back together. I did fix the digital dash in the blazer also. What do you think? Can I handle it or should I have somebody do it? I have the hanes manual for the blazer. Just paged through it once.

Ummm.....

You have never had the trucked tuned up since 1993?

Are you serious?

Are you serious?

No, we have owned it for 2 1/2 years and not tuned it up. It had that idle when we baught it. I have no idea when it was last tuned up.

Does your truck sometime not start on the first try?

From now on, always and I mean ALWAY tuneup a vehicle when you buy it and treat it like it has never EVER been tuned up since it was made.

You really need to do this before you put on the cold air intake. What is the sense of putting a nice intake on a truck that is performaing like shit to begin with?

1.) Plugs: 6 (AC Delco CR43TS / Gapped: 0.045)

2.) Spark Plug Wire Set (Decent Brand)

3.) Fuel Filter

4.) Distributor Cap & Rotor (Replace Both)

I bought it from a dealership and I assumed they had it ready to go. They put a new alternator, battery and thermostat in it before we bought it. Like I said the idle roughness is very, very minimal and it has always sarted and ran like a gem.

Ok, that is fine, but you need to tune it up.

Replace what I said above and it will smooth out for sure.

Will do before I put the intake on. Thanks. I will let you know how everything turns out!

Also, go and get the timing adjusted properly.

Will do, just got the tune-up parts this morning deutsch fuel filter, Bosch wire set, AC-Delco plugs and conrad red cap distributor and rotor.

kewl, remember to gap them properly to 0.045.

Be real careful when replacing the cap and the rotor and wires, you can get messed up pretty quick.

Another question...on my 1994 Blazer CPI..

In pulling my stock intake out, I see that there is a hose going to a PCV valve that connects to the air filter assembly. When I put my custom intake in, what am I going to do with that hose? Am I going to have to build in a hole to my intake for that tuba also?

Thanks,
Skeeter6755

The hose going to the driver's side valve cover is NOT the PCV Valve.

That is the fresh air intake for the PCV system. The PCV valve is in the passenger side valve cover and the hose from it then goes into the intake.

The PCV intake line will have to inserted into the new intake OR you can remove the line going to the driver's side valve cover and install a PCV breather filter in it's place. This is what I am going to do soon myself.

Here is a link to what the small filter looks like.

Ahhh....I understand. Thanks for your clarification BlazerLT.
I think I will have to get one of those myself sice that would be easier also. :)

Did the tune-up on Tuesday! Everthing went well. I don't think it ever had a tune-up. Original wires, plugs could have been original also by the way they looked! (Chunks of corosion on the ends, and posts were practically gone!) Distrubutor cap was coroded and the rotor was green with corosion. Original fuel filter too! It was full of dirt on the intake side but was clean gas going through on the out line.(Thank God) I can't believe it was running so well like that! Idles the same, except it seems to have more power on take off and acceleration. Thanks for suggesting that! You just shouldn't assume that a dealership is going to do these things before they sell the vehicle. I will NEVER assume that again! Next is the intake. Should be here tommorrow according to Fedex tracking. Thanks again and I will let you know how the intake goes!

So do you leave the PCV disconnected if you put a breather filter on the fresh air intake side? Or do you put a breather filter on each vavle cover?

Actually, leave everything stock.

Just off the phone wit a hot rod shop and they said it makes no difference.

Replace your PCV valve in your passenger side valve cover for better idle quality.

Also, go get the timing checked out.

When timing your vehicle, you have to disconnect the brown and tan timing wire under the glove compartment going to the computer.

So the PCV has to be connected to the air intake? How do I do this? Does a hole have to be drilled?

Ok, you have a hose right now that goes from the existing intake and into the driver's side valve cover. That pipe you will have to pull out of your stock intake and stick it into the new one from K&N. Yes, there is a hole there for it and a rubber grommet for the hole so it seals when the hose is inserted.

BTW, the PCV valve you shoudl replace is in the passenger side valve cover and should be replaced. Cost $2-3.

Intake is on! Very easy to do. What a difference! The only problem I had was the heat shield had to be ground down. No problem though. Maybe that is why K & N doesn't list one for the 93. I recommend this intake to anyone. As BlazerLT said this intake will fit the 92-95 S-10 Blazers. Just look on e-bay. It was also the cheapest on e-bay. Very happy with it!! Thanks BLT!!

No problem, just make sure you have the PCV intake line hooked into the intake where it goes to the driver's side valve cover.

Also, make sure the filter is on completely tight and check all the clamps and fittings for tightness every 2-3 weeks.

Clean the filter with the kit every 6-8 months.

When you clean the filter, soak the filter like mad with the cleaner, let it sit for 15 minutes, rinse with warm tap water and sir dry overnight. NO COMPRESSED AIR!!!

Then reoil the filter well but not too well.
