Hi , I want to buy the below said item for my Jeep, but am not sure if it will work as they said please help,
1999 2000 2001 Jeep Grand Cherokee V8 Dual Air Intake
Is this one of those cyclone cartridges you put in the intake hosing? if so then dont waste your money, the power gain off of one of these is not noticable and the fuel economy wont change enough to make a difference, the engine is gonna draw air in at whatever rate it will, the only way to change that is with forced air induction (ie turbo, supercharger, blower). these things only help to mix the fuel with the air a little better so you get a more even burn and less wet spray fuel making it into the cylinder. forced air induction works by changing the volumetric efficiency of your engine, say you have a 4L engine, running naturally aspirated in 1 cycle that 4L engine draws an average of 85% of that 4L, if you put on a turbo or blower or supercharger you make that engine draw in more than its 4L capacity so your 4L engine would be running at say 120% of that 4L, trying to compress that much more fuel/air mix is where you get all the extra power from. ill save the explanation of an intercooler for another day....
Testimonial: "thanks for saving my money 100% good comment"
if you do decide to go with forced air induction you will have to replace the head gasket for a thicker one to lower the compression while your turbo or supercharger are not making power, if you do not, you will very quickly blow your current head gasket, could shatter compression rings or come across a whole other load of problems. i personally would recommend a turbocharger as although you do get a slight "turbo lag" they are safer to drive in poor weather conditions as the compression drops off when you take your foot off the gas, a supercharger however will keep forcing air even after you take your foot off the gas.

Hello thanks for replying,
if I decide to go for supercharger or turbo, is there any thing else that will need a replace on my engine?
